How to choose the next hero
Compare the Power shown on the hero card with the weakest equipped slot. Equip the higher value first; keep rarity, appearance, and mutation as secondary checks until their effect is visible. This prevents an attractive but weaker pull from lowering active damage.
When to use a Battery
A recent speedrun shows a battery applying a large Luck boost to a limited number of upcoming rolls. Prepare inventory space and Auto Roll settings first, then use it immediately before the intended rolls—not while navigating menus or fighting.
When to leave a zone
Move forward when the current enemies die quickly enough that Gold and XP keep flowing. If the next area turns each kill into a long stall, return one zone, improve active Power or damage, and try again. A higher zone is not progress if income per minute collapses.
