XP

XP is a currency used to purchase regular battlers, base upgrades, and to upgrade battlers. It can be obtained by beating Stages. XP used to be purchasable with Bricks in the shop before it was changed to Double XP minutes. A different amount of XP is given to you upon completion of a stage, based off the difficulty setting, whether or not you've completed it before, how hard the stage is. Generally, you receive the most amount of XP from playing the hardest stages on the hardest difficulty (Tumore). You also receive more XP with different star difficulties and XP boosts.
XP Boosts are temporary enhancements that double XP gains on stages with XP rewards for a limited time. Their duration decreases only while you are actively playing through a stage. You can extend their duration by compensating for rolled duplicates in Cards or purchasing extensions with Bricks in the Shop. These boosts are toggleable, allowing you to activate them during grinding sessions or other strategic situations to maximize XP gains, or deactivate them to conserve their duration for future use. If you select a stage without XP rewards, the boost is automatically disabled and can only be toggled on again when you choose a stage with XP rewards.

 XP is used for:
* Upgrading Battlers
* Unlocking normal battlers such as 
* Purchasing base upgrades

==Calculating XP Per Time Period==
There's been numerous occasions where grinding strategies label the XP gain per minute or hour depending on use case, and it's a way to see if the strategy is the most efficient than other strategies. Calculations are important to ensure that its rewards are accurate, as if some strategies label its rewards that are too good to be true. In order to find out how many XP a strategy gives per minute or on a time period, this is the way to do this:
*Find out the completion time of the strategy that you use or want to know the XP gain of, as this will be useful for checking how many clears in a minute. You can be able to know the completion time by doing the strategy yourself and check the completion time on the Victory Screen or checking a video that showcases that strategy and finding the part where you will find the Victory Screen. However, sometimes, the completion time may be inconsistent (due to many factors like unit timing) and/or absent (if the strategy video is recording a older version of the game, however this is extremely rare), so try your best to find the most accurate completion time as possible, NOT including loading times.
*After getting the completion time, you can now determine how many times a stage can be cleared in one minute by using that strategy. Divide the completion time by 60 seconds (60 / Completion Time = Number of Completions per Minute.) If the answer is decimal, round down regardless of the first figure in the leading decimal.
After that, there are two ways to calculate the XP gain. These two ways may give the same answer, but one of them may be convenient for you.
*The first one is multiplying the XP gain per match by number of completions per time period:
*# For calculating XP per hour, multiply the number of completions per minute by 60. For calculating XP per day, however, multiply the number of completions per hour by 24. Otherwise, leave the number of completions by default.
*#Now multiply the XP per match by the number of completions. The result will be the final amount of XP gained. (XP per match * Number of Completions = XP Gained)
*The second one is multiplying the XP gain per match by number of completions per minute:
*#Multiply the XP per match by the number of completions per minute, and that's where you get XP Gained per Minute. (XP per match * Number of Completions per minute = XP Gained Per Minute.)
*#For calculating XP per hour, multiply the XP gained per minute by 60. For calculating XP per day, multiply the XP gained per hour by 24. Otherwise, leave the XP gained per minute by default.
However, if you want to check if the result is true, then you have to use the other method that isn't used. For example, if the first method is used to solve then the second method can be used to check and vice versa.
There's also one more factor that needs to be tackled: the average XP gain. Some people want to know how much they're getting on average, not the most that they can get. In order to get the average XP gain, here's how it works:
# Get the average XP per match. In order to do that, you need to get the minimum XP and the maximum XP within the XP range given. Add them then divide it by two. The following equation: ((Minimum XP + Maximum XP) / 2)
# Get the number of completions per minute from earlier calculations, as this will be useful for calculating average XP gain per minute. To find it, multiply the average XP per match by the number of completions per minute. For getting the average per hour, multiply the average XP per minute by 60. For getting the average per day, multiply the average XP per hour by 24. Otherwise, leave it by default. This is derived from the second method of solving for XP gain.
# Alternatively, this can also derive from the first method of solving too. You need to get the number of completions per minute then multiply it depending on the time period. For per hour, multiply the number of completions per minute by 60. For per day, multiply the number of completions per hour by 24. Otherwise, leave the number of completions per minute by default. After that, you can multiply that number of completions to the average XP per match.
# In order to verify the average, we need to use the XP range that is based on the chosen time period and find its midpoint. This is the same as the first point, adding the minimum XP and the maximum within the XP range given and then dividing it by two. Do note that the minimum and the maximum must have the same per time period, and the result must match the average. The example equation for per minute: ((Minimum XP per minute + Maximum XP per minute) / 2)
Now that there's ways to calculate the XP, let's give an example. Let's say that you want to know the grinding reward from a strategy that reaches 22-23 seconds in Rocket Arena. The fastest completion time is 22 seconds, albeit these completion times can give you same results (if that were the case). The reward for this stage is 4330-5293 XP. What will be the XP per hour and its average?
*Firstly, we have to identify the fastest completion time which is 22 seconds. We will divide it by 60, and it gives us 2.73 completions. Rounding it off will give us 2 completions per minute instead, which is what we need. For an alternative route, we will use the other completion time which is 23 seconds. Dividing it by 60 gives us 2.6 completions, and rounding it off gives us the same result: 2 completions per minute.
*Now, we have to choose one of the ways to calculate XP. We will use the second method (but you can use the first method if it's convenient for you.) Multiply the stage reward which is 4330-5293 XP by the number of completions per minute. Doing so will give us 8660-10586 XP per minute. We're looking for XP per hour, so multiply that by 60. This gives us 519,600 - 635,160 per hour as our final answer.
*In order to check that the result is true, we will use the other method that isn't used, which in this case, the first method. We get the 2 completions per minute from the previous calculations and we multiply the completions by 60. It is now 120 completions per hour. Now that we have the completions, we can multiply the stage reward. Doing so gives us the same result: 519,600 - 635,160 per hour.
*In order to get the average XP per hour, we must get the average XP per match by adding the minimum and maximum within the XP range provided, which is 4330-5293 XP. Adding this will give us 9623 and dividing it by two will give us the average XP per match: 4811.5 XP per match.
*We get the number of completions per minute from earlier calculations and multiply it to the average XP per match, giving us the average gain of 9623 XP per minute. This is like reverting the previous division, but this can change based on the number of completions. Since the time period is per hour, we must multiply the average XP gain per minute by 60. Doing so will give us the average gain of 577,380 XP per hour.
*We have to verify these averages, so we will need to get 2 XP ranges from 2 different time periods which is per minute and per hour. The XP range per minute is 8660-10586 XP. We will add them and then divide it by two. The result will be the same: 9623 XP. We also need to verify the average per hour, so we will do the same for the XP range per hour which is 519,600 - 635,160 XP. Doing this will also give us the same result: 577,380 XP. So that means, both averages are now verified and correct.
So 519,600 - 635,160 is the XP per hour while its average is 577,380 XP per hour in the 22-23 second strategy of Rocket Arena. However, this is one example and there could be many more. There are also situations that requires tweaking of calculations like, "What if the completion time of a strategy exceeds one minute?" and "What if it includes loading times?" These situations are a bit beyond the scope of this section, but it is up to you to find out how to solve these.
==Strategies==
Leveling up battlers requires a huge amount of XP, and in order to get XP, you would need to repeatedly beat a stage, or just through progression. Grinding a stage is the best way to get a lot of XP, but efficiency and speed is required to get large amounts of XP in the shortest time possible. Here are the grinding strategies that are made for that purpose, with added calculations previously mentioned to ensure its authenticity. Do note that these grinding strategies do not work on Tumore difficulty unless it's specified.
*Repeatedly beating The Battle Begins (Only for beginners or beyond)
**Players have found that this stage takes the shortest amount of time to complete, while still giving around 330-403 XP per completion on Normal mode. Since this stage can be completed around twice per minute and this number can be doubled. With maximum luck, you can receive 48,360 XP per hour and 1,160,640 XP per day. It is possible to beat this stage with one , provided it is at a high enough level. However, unless you have no other strategies available to use (which may be very rare depending on the situation), don't use this strategy as the reward is too low even if completion times are shorter depending on what unit/s you use. 
***You can also do it on Tumore and get more XP from this strategy alone. This doesn't change anything (efficiency and speed wise), but it can enhance the grind of this stage.
*Repeatedly beating Rocket Arena (Only for players at mid-game or beyond)
**By using rush units, you can clear this stage out with ease at around 22 to 23 seconds as the fastest time (as of Booster Pack 3), gaining XP quickly and efficiently. Using the fastest strategy in this stage, you can gain around 519,600 - 635,160 XP per hour; and 12,470,400 - 15,243,840 XP per day (Average XP per hour: 577,380; Average XP Per Day: 13,857,120). Units which are best suited for this are , , , , , , and . Ignition is the recommended bank here due to a rework that it had, making it better for grinding. 
***However, you can bring , and some units that can follow closer with him and not go past him as he had a recent update where he can sacrifice units to boost his rage attack, but you have to time it correctly in order to pull this off. It's recommended to use this strategy on 3 Stars due to having a long completion time, clocking in at 40 seconds. However, it may give more XP than on one star, but the difference between them is too minimal. (XP Per Hour: 519,720-635,220; XP Per Day: 12,473,280-15,245,280) (Average XP per hour: 577,470; Average XP per day: 13,859,280)
*Repeatedly beating Galleons (Only for players at mid-game or beyond)
**This is the same situation as with Rocket Arena, as both give the same XP and have similar bosses. However, Anti-Red units such as can defeat faster than , with the fastest completion times just above 20 seconds (19 seconds as of Booster Pack 3). The fastest strategy on 1 Star gives about 779,400 - 952,740 XP per hour, and 18,705,600 - 22,865,760 XP per day (Average XP per hour: 866,070; Average XP per day: 20,785,680). Additionally, the stage length of Galleons is 20 studs shorter than Rocket Arena, giving you a quicker completion. Detonator is the recommended bank, though Powerhouse is also a viable choice (Ignition when optional, it's the best option for this). Units which perform exceptionally well are /, the aforementioned , /, /, and , although viable substitutes such as and are also available. Additionally, use other high-speed units you can buy with the surplus of cash you'll gain. The difference between 1-star and 2-star Galleons for grinding is minimal, but 2 star is preferable because of more XP per completion and less time spent on loading screens.
*Repeatedly beating Bomb Rush (Only for players at mid-game or beyond)
**This stage can be the most efficient for grinding when one unit is used. should be the ideal unit for this, as the completion time will be 6 seconds, faster than Rocket Arena and Galleons. Not only that, this stage with can allow clears up to 10 times per minute, tripling the XP gain. For 1-star, it gives 540,000 - 660,600 XP per hour and 12,960,000 - 15,854,400 XP per day (Average XP per hour: 600,300; Average XP per day: 14,407,200). For 2-stars, 810,000 - 990,600 XP per hour and 19,440,000 - 23,774,400 XP per day (Average XP per hour: 900,300; Average XP per day: 21,607,200), surpassing the XP gain of 1-star Galleons (and its average XP gains!). There are no required banks, but Ignition can increase the XP gain by shaving off 1 second requiring precise timing for enhanced efficiency. 2-star runs are recommended due to increased XP gain per completion, shorter load times, and manageable consistency compared to 3-star runs where spawn rates are not slowed down unlike the other stars. 
***However, in order to pull this off, you have to level up Early Economy and Bank Income to the point that can be deployed at the start of the stage depending on the Stars. The levels required for must be Level 13+ for 1 Star and Level 21+ for 2 stars. You only need one to clear the stage, and needing more than one is not feasible.
