Favored Enemy
Effect:
Choose a specific monster type (e.g. aberration, beast, construct, demon, dragon, giant, humanoid*, ooze, plant, or undead). The crit range of your ranger attacks against that type of enemy expands by 2.
*Choosing humanoid: Unlike other favored enemies, choosing humanoid as your favored enemy takes up two ranger class talent slots.
Adventurer Feat:
You can change your favored enemy by meditating when you take a full heal-up.
Champion Feat:
Your crit range for attacks against favored enemies expands by 1 (to +3).
Epic Feat:
Choose a second non-humanoid monster type as a favored enemy.
