Racial Psi-like abilities available after Level 1
 

I'm converting a couple 3.5 races that have psi-like abilities 3/day which is easy to add.

However, these abilities have a manifester level of 1/2 Character Level (Minimum 1) and some abilities are only available at character levels 3, 6, 9 , or 11.

I assume I need Eval Scripts for the Manifester Level and the Level of Availability, but I have no idea what to use to pattern it off of as I usually do.

Help!
