Progression Guideline

Last updated 12/03/2022
=Room 1 to 700 New to the game=
Best weapons of choice, Sword + Staff combo
You're farming relics at this stage of the game and without the Card function (at 700), you cannot unlock V2 skills yet.
Return as often as you can, using rush at the end to farm Relic pieces and unlock them for more stat.
Spend your Gems on A + S costumes that unlock Attack, Skill dmg and Crit status. These stats are permanently unlocked and will work on any weapon.
Also unlock the skill runes along the way.
Train all your weapons to maximum proficiency for more stats.
You get roughly the same exp at all stage of the game so forcing yourself to dive deeper won't make you level faster.
For Fairies, Sinbad is your best until you have a full SS roster. Early on, just mix in other damage fairies you have with good damage as only low rank Sinbad is that good.
=Room 700 - 9000 Unlocked the card function and start farming gears=
You can now obtain cards and enhance your weapon playstyle and make them so strong you won't use weapon swap for a long time.
You need to push to stage 4000 to get 8 slots unlocked, and now you can play whatever you like and their power level will differ based on how much you invest in all the costumes and rune slots + high rarity cards.
Room 4000 is when you start to buy SS Costume for your weapon you will be maining.
There are now 3 SS costume piece per category per weapon. However, the 2 more recent pieces require you to be using V2 skills which need all 8 cards slots. Grab the cheap older ones first, as they will affect your skills fully. The only one you can grab early and receive full benefits from is Admiral's Bow.
For fairies, Pre-SS, you'll still be using Sinbad. With maxed out gear and 40%+ Crit chance, add in an A Glacio. 3rd fairy is just whatever the best one you have beside those 2.
After Room 5000, you will unlock SS Relics, requiring around 150,000 relic pieces to complete. 5 new relics have been added that are a must-get to help you farm much faster; They are Soul of Hymnal, Darkness Stone, Phoenix Feather, Exotic Amethyst and Master's Sleeping Mask. Prioritize unlocking and upgrading these then go back to farming keys and just upgrading relics along the way. No need to focus on getting all SS relics upgraded as soon as possible.
=Room 9000+ Endgame farming=
This is where you start to dive deep daily and farm golden keys, ending the push at room 9000 or even deeper like 11k and so on.
This will assume you have a full level 50 SS gear, full relics, full S card decks at minimum, full SS fairies and all the required costume+skill runes unlocked.
It might take a month or two to reach this point.
Thanks to the latest update, all weapons are strong enough to stomp their way to 13.5k where you get the last reward chest and start returning to farm for more golden keys.
However, not every weapon requires the same amount of investment to reach their full potential where you just farm up to 13-14k over and over to get many keys per day. Below is how each weapon ranks based on how cheap and easy it is to get the weapon to function:
1) Staff - Staff at the current state of the game has the best damage and can push to 14k the fastest but has the worst farming speed later on when other weapons catch up.
2) Greatsword - The most versatile weapon after Staff thanks to the recent buff. Easier to get into from the start of the game along with Staff.
3) Dagger - Farm slightly slower than GS but can push faster, no where near as fast as Staff. Need a lot of runes and SS costumes.
4) Bow - Very expensive weapon now but will have top and consistent speed. Need everything including specific cards too.
For fairies, use SS Glacio, Olla and Nix for the best farming. Use Sancho instead of Nix on GS.
