Battle Formation

Battle Formation is a functionality that is unlocked at Player Level 72 and can be accessed from the Town in the Arsenal menu. Similar to Faction Rosters, it allows players to focus on improving the power and effectiveness of units of a specific Faction and encourages playing specific factions instead of spreading them around.
No Battle Formation exists for Neutral faction.
=Upgrade=
In order to upgrade Battle Formations, the player requires two elements:
* "Energy Cores" - a specific currency used only by Battle Formations obtained through Alchemy. Every faction has its own Energy Cores.
* Specific units tokens of that faction (most often R and SR). This ties the functionality to some degree to the Barracks.
==How it works==
Upgrading each Battle Formation must be done one level at a time. To upgrade a level, the player must first Activate individual nodes.
The nodes are placed in a graph and need to be Activated in a certain order (starting from the center). Once Activated, each individual node grants specific global bonuses to units of the formation's Faction that can either be offensive (Unit Damage, ATK, Accuracy, Critical Hit) or defensive (HP, DEF, Unit Damage Reduction, Dodge, Tenacity).
There are two types of nodes: smaller and bigger. The smaller ones cost less resources, don't require unit tokens to upgrade but also grant a smaller bonus than the bigger ones. The number of nodes increases as the formation level increases.
Once all nodes have been unlocked the player progresses to the next level and gains a significant passive bonus for that Faction's units.
There are a total of 12 levels.
=Alchemy=
This functionality allows the player to produce "Energy Cores" that can then be used to unlock nodes.
To access the Alchemy menu, the player must go to the Shipyard's central island.
==Alchemy Potion==
Producing faction Energy Cores requires Alchemy Potions. This is a universal currency (independent of faction) that can be obtained by refining either Skill Stones or Materials (similar to upgrading unit skills).
Note that books are particularly effective and recommended for this. Here are the equivalent costs:
Material	Alchemy Potions

 	1125
 	2500
 	150
 	300

Book 4 	900
Book 5 	950
 	25
 	50

 	320
==Refining Cores==
Players can refine cores by spending energy potions. There are three tiers of formulas (green, blue and purple) that randomly appear in a list. Players can select which formula they want to refine, or refresh the list for free up to three times per day. After that a small diamond fee has to be payed for each refresh.
Once a formula is selected a specific amount of time must elapse before the resulting cores can be claimed (a random number selected from a specific interval based on tier)
Formula Tier	Alchemy Potions Cost	Time 	Equivalent Cores
Green 	20K 	60min	30-45
Blue 	40K 	2h 	90-135
Purple 	80K 	4h 	235-355
Based on the costs and resulting amount of cores, it is highly recommended to only target specific faction(s) and only use purple formulas.
