Robe of Shadows:
Thursday Thaumaturgy

Be sure to check out The Cursed Tome of Mar-Karakor and The Cursed Tome of Mar-Karakor pt2 for some good old-school spells.

I’m going to make a clerical version of one for my current campaign:

Robe of Shadows

Level: C2
Duration: 1 Turn
Range: Caster

The caster is draped in writhing shadows, granting a -2 bonus to AC.

It fits an NPC cleric and her godling perfectly.
