Not sure if it will be in v0.3, but more consumables will come, and hotbar usage will be a good improvement. I also plan to add a 4th rarity for items that will have abilities assign to them for a few casts.
Would charges for said items be able to regenerate? I'm trying to get more into ToME inbetween your updates and I like how they handle item charges like this. Basic example:
Recall Rod (Teleports player to world map) has 400 charges, using 201 per use. 1 Tick I think regenerates per turn.
Sounds like could have some headaches associated for this game, maybe if charges only regenerated when the item is held by the player, it'd alleviate some of that?
Whatever direction you go I'm excited to start playing with whatever you've got coming down the pipe :D
