Item rarity and its Color system.
The current color system feels off to me, feels like Blue should be after green. Making it Common, Rare, Mastercrafted, Artificer, Relic.
Changing Common tag to Battle Worn, and Rare tag to Well-Kept.
Making the rarity. Battle Worn(Grey), Well-Kept(Green), MasterCrafted(Blue), Artificer(Purple), Relic(Gold).
This would be more lore correct in my opinion as well.
Noticed that some weapons, their skills are able to stack their use on top of each other.. (Ie, Grenade Launcher, making it just about better then the cyclone volley skill if used in the right order. #2,#1,RightClick,LeftClick.)
The angle in-which he's holding the sword makes the main-actors arms seem unnatural, the wrist is at a 90 degree angle to the forearm, and pulled close to the mid-body region. Holding the blade point straight up or angled more to the front would seem more natural to me.
