Beholder eyes... ignore spell resistance?

Supernatural Abilities (Su)

Supernatural abilities are magical and go away in an antimagic field but are not subject to spell resistance, counterspells, or to being dispelled by dispel magic. Using a supernatural ability is a standard action unless noted otherwise. Supernatural abilities may have a use limit or be usable at will, just like spell-like abilities. However, supernatural abilities do not provoke attacks of opportunity and never require Concentration checks. Unless otherwise noted, a supernatural ability has an effective caster level equal to the creature’s Hit Dice. The saving throw (if any) against a supernatural ability is:

10 + ½ the creature’s HD + the creature’s ability modifier (usually Charisma).

And the beholder...

Eye Rays (Su): Each of a beholder’s ten eye rays resembles a spell cast by a 13th-level caster. Each eye ray has a range of 150 feet and a save DC of 17. The save DCs are Charisma-based.

As (Su) ability and not spell-like they ignore resistance...

So if a Master of Many Forms with at least one Assume Supernatural Ability become a Beholder he can attack without worrying about SR.

I am missing something?

No, that'is indeed the case.

Really, mostly the fault of Assume Supernatural Ability being silly broken.

Not like a regular wizard has to worry too much about SR anyway
