Can an Eidolon apply a reach evolution to a weapon attack (such as a polearm)? The wording of the reach evolution does not seem to refer to natural attacks as most other Eidolon attack abilities do.
One of an eidolon’s attacks is capable of striking at foes at a distance. Pick one attack. The eidolon’s reach with that attack increases by 5 feet.
When combined with a reach weapon, it seems this could easily grant a 15 foot reach. This seems to be very powerful at low level and I have concerns if this was intended.
