First off I think the stim (free shadow moves for 15 seconds) is too powerful for the cost. It’s effect is particularly good against the omens, so it should be more restricted. the much more expensive versions that come with a second buff are good, but the item that only costs 4 nano-fibers should probably just reduce meter usage by 25% or increase meter gain or something like that.
That is my most major concern at the moment, feel free to discuss this or post other consumable related concerns here.
