Abilities 5 of Backwoods Courier

Neither Rain nor Sleet...

Self

You do not need to do anything special to trigger a Self ability. When you use it, it affects you.

Calm

You become immune to Frenzy and Taunt effects, but vulnerable to Sleep and Soothe effects. You may not willingly end your Calm, but others can end it with a Rage or Rouse effect.
