Alter Self on Large Synthesist Eidolon

[Nephatrine]

So let's say we have a Synthesist Summoner from Ultimate Magic. This basically combines you and the Eidolon into a single entity. Taking the Large evolution, you make yourself Large and get a large number of modifications to your stats which appear to mirror those listed in the Bestiary for moving from Medium to Large like +8 Strength and +2 Natural Armor. If you then use Alter Self to make yourself Small, what does that do to your ability scores? Do you still get to keep the +8 Strength and whatnot from the Large evolution.

My gut says that you'd pretty much lose everything from the Large evolution while Small since you only really get those as a side effect of you being Large, but I'm not sure the RAW backs that interpretation up. Anyone have any thoughts on the matter?

i´m pretty sure the adjustment table in the polymorph sub-school section of the magic chapter covers that.

Ah, you're correct. I didn't even realize that table existed. It doesn't completely counteract the bonuses from being Large (only half, in fact) but it seems a lot more balanced now. Thanks.

I always counted evolutions as racial abilities, i.e. they are lost/supressed when the Eidolon is under the effects of a Polymorph spell, but any bonus that doesn't come from an evolution is left intact.

Dunno if that helps, but I figured I'd give my two cents

A Synthesist can use Reduce Person on himself without the losses from Alter Self because its not a polymorph spell per RAW. You would lose 2 STR but gain 2 DEX. Granted it would not make you Small but it would allow a Huge Synthesist to squeeze through tight spaces.
