I'm thinking about taking the feat Pin Down for my Eidolon. The feat has 2 requirements: Combat Reflexes, and Fighter lvl 11. Can an Eidolon quilify for this? If initially no, is there a work around?
Eidolons have no class levels, so cannot qualify for feats that require them. I know of no work around.
They can't qualify for pin down, but other feats might have similar enough effects. e.g. difficult swings (prereq martial focus since it won't have weapon training.)
Eidolons have no class levels, so cannot qualify for feats that require them. I know of no work around.Ancestor Eidolon. A Fighter Creature is "is considered a fighter with a level equal to its HD for the purpose of qualifying for combat feats". You'll never qualify for Pin Down though, since the effective fighter level for an Ancestor Eidolon maxes out at 10 HD when the summoner hits level 20 (and the practical max is Fighter 5 at Summoner 12). This does allow qualifying for Difficult Swings though since it also gets Weapon Training.
Good call, but that subtype's text is pretty confusing. So, I think the eidolon uses its own hit dice for feat prerequisites.
For any effect dependent on class level, an ancestor eidolon uses its total Hit Dice instead (such as with the human’s skilled racial trait).
That text about gaining abilities at levels 5 and 20 seems to be talking about the rate of gaining new abilities and not the scaling of other abilities.
