Item: Slippers of the Tank: each contains a functioning firearm fired by flexing one’s toes. The treads can be used to move at half standard speed but on any terrain.
Item: Shoes of Tentacular Clambering, with dextrous living tendrils that allow the wearer to walk as if wearing elegant heels on any terrain, plus a grappling-kick attack.
Item: sandals ornamented with the eyes from a Beholder’s tendrils, but not sure which ones; whatever it is, in their desiccated form they cannot fire the rays that cast the spells, but the wearer can cast them through a successful touch attack. This could be by touching them gently with the sandal or even throwing it at them, but let’s be honest, what player is going to pass up the ability to turn monsters to stone by kicking them? Roll d10 once per sandal (so probably twice if you get a standard set, but maybe you just find one since even I know giving this one is unbalanced, &c.)
