My friend plays an Unchained Summoner in Pathfinder Organized Play, and I build a character for them. It's actually possible that I create my own Unchained Summoner two, as I've tried this class already and kinda liked it.

I'd like to maximize overall damage dealt per round. As my Google-Fu shows, most people speaking about Eidolons give them either a lot of Natural Attack or build them for archery. However, I would like to try a (possibly) even more damaging thing.

I'd like to give an Azata several pairs of Limbs (arms) as it progresses, and make the said Azata wield a Greatsword in each pair of limbs. This answer says that there is a special feat for that called Multiweapon Fighting.

The earliest point when this feat can be taken is level 3: you cannot qualify when you are level 1.

Will this actually give a better damage per round than a natural attacks-based build?

Is the same possible with multiple bows used in each pair of limbs?

If it's worth it at some point, does it always stay powerful?

PFS rules are used, hence it's not important what happens after character level 12.

  • \$\begingroup\$ None of the feats from Bestiary 1 are legal for play for PCs, animal companions, or familiars unless specifically granted by another legal source; And Eidolons don't have anything that would grant them the feat ( unlike Animal Companions who explicitly get access to Improved Natural Attack and such). \$\endgroup\$

Not really.

At level 3 you will have a base melee to-hit of +7 (3BAB + 3STR + 1bonus, not counting any feats or other build-agnostic enhancements). With extra pair of limbs and Slam evolution for them you get 2x claws +7 (1d4+4) from base biped form and 2x slams +7 (1d8+4).

With 2x greatswords you get two attacks at +3 (2d6+6). Both to-hit and sum of damage are lower.

I haven't tried building it any further, but I suspect the natural attack build will get even further apart as you go.

Similar thing would happen with bows, even worse with eidolon's Dex being a 4 lower for extra -2 to-hit.

  • \$\begingroup\$ Wait, is it possible to have both a Slam and a pair of Claws on one pair of limbs? \$\endgroup\$ Jan 26, 2019 at 23:12
  • \$\begingroup\$ No. Bipeds start with a pair of limbs and 2x claw attacks for free. At third level you get 3 evolution points, enough to get a second pair of hands (2ep) and get Slam for them (1ep). \$\endgroup\$
