Quick question. If I have a bipedal Eidolon with two claws, if I take the Reach evolution, do both claws have reach, or just one?
As per mentioned in the FAQ: Only one would gain the benefit.

Summoner: If I choose the reach evolution for my eidolon, how many of its attacks gains increased reach?
The ability description says "pick one attack," not "pick one attack type." So if your eidolon has two claws and you pick "claw" for the reach evolution, only one claw gets increased reach. (The reach evolution is intended to let you emulate having a dragon-eidolon, as a dragon's bite attack has greater reach than its claws.)

Just one. The intent was for things like dragon-eidolons and their bite attack. But 1 reach claw is surprisingly useful.
Gotcha. Thanks!
