@biome chest items
Did some testing with same tier armor/accessories/enemies (at master).
I think their damage dont need big changes. But some notes here:
Vampire Knives:
Good as a secondary weapon because it has lifesteal. Can also be used by non-melee player. It looks like melee speed has no impact in fire rate (intended?)
Scourge of the Corruptor:
Very good vs many enemies. All fine. Maybe even a little too strong. But I think thats fine because its a biome chest weapon.
Piranha Gun:
Damage OK but handling not that nice. They often dont spread that much from each other and fly in a random angle which dont need to be equal to the targeted mouse position. If they dont hit anything they will fly back. That means it depends at luck if you hit a distant enemy. Not that nice for such a long attack animation time.
If they dont find a new target after killing some enemy they fly back. Often hard to see if only one or two did fly back.
Some ideas how it could be changed:
1) For first target they fly united in a straight line (at clicked position) and spread after hitting their first target. Two of them will try to find another target in close range if nothing else there they will attack the same target.
2) If one Piranha can't find another target in his range it will check for possible targets in rage of his mates.
3.) If no other enemy nearby they will attack the same target until a new target is in close range
4.) If all have no new targets in range they move all together back to the player
Rainbow Gun:
Damage Ok. Nice to have (as Hyperkatmanders wrote) would be some longer horizontal line (maybe +5..15 blocks) and/or even better some longer duration (25+ sec)
Staff of the Frost Hydra::
Damage Good as single sentry. Multiple Frost Hydra sometimes not that good because e.g. 5 Frost Hydra aiming at a single target often do only 1-2 damage instances at the target.
A little boring because it has no fancy unique/rare attack pattern as the other biome chest weapons.
Desert Tiger Staff:
Damage good but is it intended that he wont attack anything below the (flying) player (30 block range) but enemies at 50 horizontal range?

[..] but we can't get both evil biome weapons in the same world? I mean it feels like we should be able to get both in 1 world[..]
with easter egg seed 5162020 you can have both of them in one world
