Wait a sec, shouldn't the psionic Psi-Like Abilities be (Ps), not (Sp)?  Also, I think we need to say "at will" before the first group on the monarch.
		
		
	 
That's odd. I thought I'd corrected that (Ps) error months ago.
And yes, it should have an At-will in it.
Updating 
Monarch Scorpion Working Draft.
...upon reflection, I think I corrected the Monarch Scorpion's PLA/SLAs but didn't fully correct the Master version. 
	
		
	
	
		
		
			As for frequency, let's say 
at will -- control body, claws of the vampire, read thoughts, adapt body, inertial barrier, immovability, telekinetic force, telekinetic maneuver, telekinetic thrust, create sound
3/day -- psionic dominate, ectoplasmic form
1/day -- suspend life
Does that work ok for you? I don't mind shifting some of those around if you prefer.
		
		
	 
Hmm... that's an awful lot of At-Wills. We've got 10 of them to two 3/days and a single 1/day. I think we'd better move at least some of the At-Wills to 3/day to spread the fun about.
Let's sort them out by level:
1st: create sound
2nd: read thoughts
3rd: claws of the vampire, 
ectoplasmic form, 
telekinetic force, 
telekinetic thrust
4th: control body, 
immovability, 
inertial barrier, 
psionic dominate, 
telekinetic maneuver
 5th: adapt body
6th: suspend life
Hmm... how about if we make 
adapt body, 
ectoplasmic form, 
immovability and 
psionic dominate 3/day?
I'd also considered moving the three telekinetic disciplines to 3/day and shifting 
ectoplasmic form to At-Will. Mainly because the SLA equivalent 
telekinesis is two levels higher than 
gaseous form, but at-will telekinesis seemed more appropriate for this beastie.
	
		
	
	
		
		
			Your proposed SLA equivalents are fine by me.  I don't quite know how to match to adapt body, either.  Maybe resist energy plus water breathing?
		
		
	 
Well ideally we need a 5th-level spell that does something more-or-less-similar since 
adapt body is a 5th-level power.
Unfortunately, there is no such ability in the SRD and
resist energy is only 2nd level versus the 5th level of 
adapt body.
Maybe make up the difference with metamagic? Hmm... I suppose quickened 
resist energy would be a pretty close match out of what's available. That's allow the SLA version of the Master Scorpion to "instantly" switch to a particular form of environmental damage.
However, 
adapt body does not include energy resistance as such, it just reduces the damage from the environment - so arguably it provides no protection from a 
fireball. It's more like an extra-strong version of 
endure elements plus 
water breathing.
Maybe we should give it this as a special SLA of some sort rather than try to fit a square peg into a round hole?
