Thank you for your feedback)
Healing, yea, we haven't implemented it yet)
Nice feedback about pick up range, I really haven't thought about it like ever, it makes no sense in current scenario indeed)
Regarding trinkets- that's a heavy work in progress, whole system will be rewamped afterwards, as well as interactions and progression
Regarding abilities- active ability (as well as auto attack and trinkets) are tied to a slot, where weapon is currently in, so any weapon, that is in a 3rd slot- will be an ability (AoE damage for Kama, Dash for Bow and Force Push for Spear). Damage amplification and status effects affect Ability slot itself, regardless of what weapon it is (excluding Bow, because Dash has no damage component as of now)
Thank you, will keep up improving and shaping our game)
