Definitely, that name's great. And some items could be something like, oh, I don't know, throwing stars, maybe? Like it's a charged item, with like 5 charges, and it gives the hero a secondary attack until you use it up. For instance, like the ability firebolt, and change the missile art to Shadow Hunter, or Spell Breaker. Any thrown blade that spins is fine.
Or, you could add an elemental thingy like the others said. It upgrades weapons, or is just a spell that you use once. Fire Strike would be good if you converted it into an item ability and changed the name. Or Blizzard/Frost Nova, Force of Nature, Earthquake, Thunder Clap, etc.
A pendant type thing might be good too. It could give off an aura, or whatever.
Back to before about the 'shrooms. Rather than that effect, it gives you hero heightened speed/attack rate and armor, like taking drugs. Higher speed (sometimes) and you feel pain less (or so I heard). Good Luck :shades:
