Hello,
One of my players will use the Thaumaturgist Prestige class from the SRD 3.5. We will go farther than this and allow it for arcane casters (he is one) by adding the requiremant "Spells
Able to cast lesser planar ally OR LESSER PLANAR BINDING.
Which changes would you suggest for such a character? Especially the level 5 special ability isn´t so easy to convert because Pathfinder has no longer a thing like ECL.
Can the creatures (if he decides maybe for a Djinn cohort) have class levels? He will get his Cohort at level 14 (earlist because he must be level 9 wizard before he can get into the prc). Which level would have a djinn arrange his ability stats like a npc?
