Armour and special defenses Fuzzy Cloak
Good for magic users for whom wearing metal armour is inadvisable (higher spell failure). This cloak gives them the best possible result for a given attack roll . E.G. For a roll of 99 .Look along the 99 row against each Armour Type and find the lowest critical . Say it has 13C against plate , 15C against chain, 20D against RL, 21D against SL and 26E against none then the plate result is taken. Often plate is the best , but not always. Do not tell the players how it works, keep them puzzling

Demon Armour . This armour suit made from the skin of a demon gives protection as plate armour but in addition is immune to fire damage of any type. Good for the character who always seem to cop the fireball or get breathed on by a dragon.( Dick in the case of my campaign)

Shock Armour.
A fun one this. It protects as plate armour. However if an enemy is using a metal melee weapon and they hit the character an electricity crit of the same level is given to the enemy.. This is limited to 3 times per day.

Warg’s Skin Cloak .
This enchanted warg skin cloak gives it (usually a mage) user protection as for plate without the penalties for movement or magic.
