Stacking ability modifiers?


Rules Questions


i tried to look around for this, and there was a post about it but i couldnt tell if it applied to this situation

im a summoner and im working on my Eidolon. at lvl 9 he gets +3 str, i also want to make him large +8 str. i also took augment summoning for an andditional +4. i would love to take summoners call for +2 str. for a total of +17 str.

anywhere i could look to see if this is viable?


The Large and the +3 str from just being that level of summoner Stack.

The /only/ time your Eidolon benefits from Augmented Summoning is if you use the Summon Eidolon spell.

Summoners Call will Stack witht he other Bonues.

As far as Augmented Summoning and Summoners Call, they do not stack. They are both Enhancement bonuses.

Augment summoning doesn't work with an Eidolon unless you are summoning with the second level spell (the one with the short duration).

I don't have my books on hand but I seem to recall Summoners Call sucking. I'm pretty sure it was an enhancement bonus which would not stack with any stat enhancing items the Eidolon may have.

Don't forget the Eidolon boosts 1 stat every 4 hit dice.

When combining bonuses, you have to look at the types of each bonus - you only get the largest for any given type (except dodge, but you're not going to get a dodge bonus to a stat). Untyped bonuses always stack with everything except another untyped bonus from the same source.

Lets look at them all:

  • Level 9 bonus (+3): "Str/Dex Bonus: Add this modifier to the eidolon’s Strength and Dexterity scores, as determined by its base form. Some options available through the eidolon’s evolution pool might modify these scores." Nothing about a type there, so it's an untyped bonus that stacks with everything else.
  • Large (+8): "An eidolon grows in size, becoming Large. The eidolon gains a +8 bonus to Strength, a +4 bonus to Constitution, and a +2 bonus to its natural armor." No types here either, so it stacks.
  • Augment Summoning (+4): "Each creature you conjure with any summon spell gains a +4 enhancement bonus to Strength and Constitution". This is an enhancement bonus, so it won't stack with other enhancement bonuses, but we don't have one yet. Do note, though, that this only affects an eidolon if you summon it with the summon eidolon spell. The regular ability to summon it isn't a spell, so it doesn't count.
  • Summoner's Call (+2): "Whenever you summon your eidolon, it is more powerful for a brief period of time. You may give it a +2 enhancement bonus to its Strength, Dexterity, or Constitution." This is another enhancement bonus, so it wouldn't stack with Augment Summoning if you chose to apply it to Str or Con. It would stack if you applied it to Dex, because you don't have an enhancement bonus to Dex yet. This would work no matter how you summoned the eidolon.

    I hope that helps clarify.


  • wow, you guys are fast. thanks for the in depth reasoning as i am rather new to pathfnider.

    also, thanks for pointing out the facts with augment summoning. might think again about that feat.


    Thing i realized when i hit lvl 9 with my Summoner is the Eidolon is meaningless.

    Basically, the Summon Eidolon spell with the SLA is better than an Eidolon Alone.

    At that level you start geting the really useful Summons and If i did it again I Would Design with the Assumpion im using the lvl 2 spell Rather than the normal Eidolon ability.

    By this level the Eidolon is nice but isnt needed in my view. Which isnt to say its bad just your ability to Summon at this point is pretty Solid and spending 1 round to have your eidolon come in with +4 str +4 con is nice.

    Back it up with the.. Balna? Brailna.. arg stats with a B the winged woaman who casts lighting bolts mirror image and blurr and curse serious wonds.

    or a large air elemental.

    looking at the summon 1-# ability that the summoner gets, you can only have one thing summoned at a time. soo does the ability of the summoner having his eidolon out and a summoned creature differ? as in, if you just summon the eidolon for a min and have him by your side, then in combat summon a monster work? it doesnt look like it. or did you mean something else?


    Summoner's Call only lasts 10 minutes.

    Also because it is an enhancement bonus it conflicts with a variety of other bonuses like Bull's Strength...so even if you don't have Augment Summoning, you still probably don't want to waste the feat getting Summoner's Call.
