Adding a custom Feat

[bcordes5583]

Hi guys just got this at gencon today and im trying to figure out how to add the custom feat Sacred Outlaw.


Sacred Outlaw

Type: General
Source: Dragon #357

Your devotion to your deity continues to grow, even when you choose to familiarize yourself with more worldly pursuits.
Prerequisite: Sneak attack +2d6, ability to turn or rebuke undead.
Benefit: Your cleric and rogue levels stack for the purpose of determining your turning check and turning damage. For example, a 3rd-level cleric/4th-level rogue turns or rebukes undead as a 7th-level cleric.
Your cleric and rogue levels also stack for the purpose of determining your sneak attack bonus damage. For example, a 3rd-level cleric/4th-level rogue deals +4d6 points of damage on a successful sneak attack.
Special: Deities most likely to accept Sacred Outlaw: Beshaba, Cyric, Gargauth, Hoar, and Mask

any guidance would be appreciated!
