So one of my party members is a Witch Hunter, and it's clear that this 3pp class takes a number of things from other systems that weren't in PF1 originally, but I think my current issue is the lack of rules text for the Spellbane ability they get at 5th lvl.
"At 5th level the witch hunter can attempt to use the spellbane power as a standard action. The witch hunter makes a melee touch attack. If it is successful, the target is affected by the spellbane and this counts as a successful use of the ability. Spellbane functions as the targeted dispel ability of the dispel magic spell. A witch hunter may have a number of successful uses of spellbane per day equal to 3 + his Wisdom modifier."
So first off, it's been ruled that this can work against my Hexes should my own party member attack me for any reason, which sucks but we worked it out to an agreement. The REAL issue is that I don't see anything that determines the Caster Level of the Witch Hunter. Are they implying that a simple melee touch attack is a free Dispel Magic success? That seems wrong, especially with how it's written in Dispel Magic that you don't pick a specific magical effect and you have to have a roll that determines what effects you can dispel.
Am I missing something here?
Well since there is a Talent to increase the effects by +4 (Casterbane) its obviously not automatic. So in line with most abilities of that type you should consider the Caster Level of the Dispel Magic effect equal to your Class Level in the Witch Hunter Class.
That would be the simplest way to go about it.
