Druid Companion and Favored Terrain

[BishopMcQ]

When a Druid gains a Favored Terrain (such as through World Walker) does her Animal Companion gain the bonuses, the way that a Ranger's Animal Companion would?

Hunter's Bond says it functions as an Animal Companion at (Ranger Level - 3) as the effective Druid level.

[MurphysParadox]

No because you do not get Hunter's Bond, which is a ranger class ability gained at level 4. A World Walker druid does get the favored terrain feature, but that does not extend to his companion.

[graywulfe]

As the ability to pass Favored Enemy and Favored Terrain Bonuses to your Companion is part of the Hunter's Bond ability A druid who got the Favored Terrain from some other source, that did not give her Hunter's Bond, RAW their AC would not get the bonuses.

Opinion wise I would allow the bonus to go to the Druid's AC in my campaign.
