Problem is, I cant figure out the cost to make them! I have been looking at the example traps in the DMG2, and I notice some correlation between the spell turret traps and the others.
For example... All the CR5 traps cost 1400. So using this logic, I can guess that a cantrip spell turret would cost the same as a CR1 Seperation Wall Trap at 1kGP.
But not all CRs are accounted for and most do not include the XP cost. (Which I seem to recall being 1/25th?)
What is the specific formula for detirmining a spell turrets GP and XP cost?!
