Coat of Many Stars (Su)
Source: Advanced Player's Guide, p. 48
You conjure a coat of starry radiance that grants you a +4 armor bonus. At 7th level, and every four levels thereafter, this bonus increases by +2. At 13th level, this armor grants you DR 5/slashing. You can use this coat for 1 hour per day per oracle level. The duration does not need to be consecutive; it can instead be spent in 1-hour increments.
