(SWADE) Deadlands - Is a Blessed with the Hexlinger edge too OP?
TLDR: I'm toying with the idea of playing a combat/exorcist priest for an upcoming campaign. Would allowing him to take the Hexlinger Edge to have the Ammo Whammy power be too OP?
To go into more detail: I really like this idea of a penitent priest that hunts monsters as a way to absolve his previous sins. But looking into the Blessed arcane background, the list of powers seems to heavily lean on support instead of firepower. Mechanically speaking, the power Ammo Whammy (from the Hexslinger) seems way closer to what I want, but the rest of the Huckster's arcane background heavily clashes with the concept of a priest (not to mention that I've already played a Huckster so I want something different).
Both I and my DM are fairly new to the system, so before springing this rule-breaking character on him, I would like some advice on how balanced this is. Is there a combo I should look out for? Is there an appropriate nerf for the character? Is this a perfectly fine homebrew? Or is this just too against the grain of the game?
