Magic item: Glitchy Shield

Magic item: Glitchy Shield
This jousting shield of uncertain heraldry is cursed with poor collision detection – it will only defend against attack rolls that yield odd numbers.
It is prized chiefly as a climbing aid – if you bash it repeatedly against a wall, on 1 on a d6 it will get stuck half-in and half-out of it, making a handy platform. The shield can be freed again by repeated tugging (1 on a d6). Oddly, it never glitches out while a character is standing on it.

Animate Device 2nd level spell, brings any valid* heraldic emblem to life. The emblems fight as monsters with 1d6 HD and whatever weapons you’d expect (dragons breathe fire, spear-wielding wolf-boars fight as paladins. Caltrops can scuttle deliberately under foes’ feet, chevrons… do whatever chevrons do. Probably redirect traffic).
