I'm having a hell of a time trying to add a perk as an enchantment effect; I make the enchantment, add it to the armor, it has the magic effect with the perk to apply, but I cant get any of the "entry point" effects in the perk to work. If I add a spell ability to the perk in addition to the 'entry point' effects, the spell will be added properly but the entry point effects (namely, mod spell cost) don't get applied. Why is this?

Disregard, I found a work around

If you decide you still want to try this, you could post some screenshots of your perk setup in the CK, and maybe someone here can help figure out the issue. Perk entry points should work when configured correctly.

For posterity please describe your workaround, lest some poor soul have similar issues.
