uh uh uh maybe make-
-an overlay they have to press a certain amount of times to get the crystal (like… 50)
-destroying a crystal cluster in a heavily guarded base (probably with sentries or alternating lasers, just make it dangerous), only available to this class (to avoid guarding it)
-step counter: every seven dozen or so steps, they get a crystal from… like… crystal… powers
-maybe every few minutes/seconds new a small crystal cluster spawns on the map, surrounded by a small zone that deals damage the longer the player stand in it. the player can only collect the crystal by standing at a close range, so to collect one crystal, they take just about fifty damage over time, which makes it a little tricky since they’re also open to being attacked by their rivals or opponents, or others of the same class
idk if these work since i don’t know anything about the game, but the game sounds decent.
were these too easy? maybe i could spice it up later. hope these ideas work.
