Developers influence from games like Heroes of Might & Magic and classic cRPG games like Baldur Gate. When they created a turn-based strategy system, they didn’t want it to feel static, so each round of the battle you only have 10 seconds to choose your abilities and assign your action points.
You have a total of 12 action points, and you assign them to attacks and defenses depending on how you want to strategize for that turn. Once your decision is finalised, you’ll see the outcome of the selection against your opponent and determine what you need to do next.
Strategy will come in watching your opponents and what they do, as well as their patterns and moves they have. Since you only have a total of 12 action points per turn for both offense and defense, you’ll sometimes want to consider leaning more defensively.
The way the attacks between you and your opponent play out is also determined by your choice of action type. Whether your attack is zone of effect or single target, ranged or melee, player attacks of each type will take precedence over mob or boss attacks of the same type. Mental attacks are done first, which are the game’s summoners and debuffs, then ranged, then melee attacks. So if you choose a debuff first to reduce the boss power, you should land first, but if you try to punch the boss but the boss tries to poison you, the boss will hit you first.
