Serpentine Eidolon +Reach attack+Enlarge Person?

[Scrawl Da'Wall]

Howdy Folks,

I have scoured the boards and can not find a definitive answer for my APG Serpentine Eidolon.

Question #1. Can you add the one point reach evolution to a Serpentine
Eidolon(Who has reach bite as a free evolution)? Rule seems to indicate you can only ADD it once..

Question #2. You cast Enlarge Person on a Medium Serpentine Eidolon who has Tail slap & Bite with +5ft reach. He is size long so his Tail slap does not gain any reach. Does his Reach Bite attack gain any additional reach as per a reach weapon?

Thanks in advance to any replies.

No on #2. The reach evolution doesn't double reach like a reach weapon, it adds a fixed 5'.

The FAQ on reach even makes clear that when you take reach, it applies to only one specific attack, not one attack type.

Since the language for the Reach evolution does not include the language allowing you to take it multiple times, you cannot take it again. The fact that the serpentine ediolon receives it for free does not mean that they received another special ability that grants reach, but that they have THAT evolution at no cost. Since it cannot be taken twice, you cannot add the reach evolution again to your serpentine eidolon.
