Playtest is finished (took a while). Play bears out many of ruemere's concerns. I have revised as a result:
o Changed caster level to 19th.
o Allowed the sustained barrage ability to use four rays as immediate actions. I'm tempted to just change rays to use free actions, giving the beholder an extremely good ability to react to situations, but this is probably too much.
o Removed the "charm person" ability from the enthralling ray entirely. Changed the ray to "stunning ray", made it's DC a bit higher, and added a "3/day" spell-like ability to cast charm monster (without the racial DC bonus).
o Changed the mechanics of Baleful Eye to just use Spell Resistance. It amounts to almost the same thing, but uses more standard language. (Also allows for things like Spell Penetration and such.)
