I have a player who want to make a "tanky" build with a Synthesist Summoner (from Pathfinder APG).
The plan is as follows: The fused eidolon is a bipedal with dual claws. Evolutions are:
- Bite, augmented by:
He also picked Combat Reflexes, granting him multiple AoOs.
To protect the people "in the back", the plan is to prevent monsters from passing him by using his reaching bite attack and grapple the opponents on hit, like this:
- Monster tries moving past him: AoO with Grapple on hit.
He is moved to the opponent's square, (isn't he?) as per grapple rules. He isn't, see the accepted answer.
- Another monster tries to move past the (now grappled) Synthesist. He decides to take a free action to let go and follows up with reaching bite again and is moved to that monster's square if he hits.
- repeat until all monsters have moved or no AoOs are left.
Aside from it being a nice idea for a character ("No one gets past me") that made me laugh IRL, does this even work?
