This is a Feature Request.
Currently in Wrath of the Righteous, spellcasters are automatically assumed to be Casting Defensively while threatened. This involves making a Concentration Check d20 + Caster Level + Caster Modifier
vs DC 15 + (Spell Level x 2)
. If the Concentration Check is failed, the spell is lost and the caster takes an Opportunity Attack. This effectively gives all melee combatants the Spellbreaker feat for free.
By the table top rules, the caster has a choice of the following:
- Do not Cast Defensively. No Concentration Check is required initially, but casting the spell provokes Attacks of Opportunity. If the caster takes damage during the spell cast (such as from the provoked attacks), they must make a Concentration Check vs
DC 10 + Spell Level + Damage Taken
or lose the spell. Half of any continuous damage taken by the caster (such as from a Bleed effect) is also included in the Damage Taken.
- Cast Defensively. A Concentration Check vs
DC 15 + (Spell Level x2)
is required. Failure causes the spell to be lost, but does not provoke an AOO.
So in table top, the player gets to chose whether they want to gamble on their chances of avoiding the AOO damage (possibly through high AC, concealment, DR, etc), or take the harder baseline check in favor of not provoking. WotR assumes, perhaps fairly, that melee casters will always opt to Cast Defensively, but giving Spellbreaker to everyone and their mother is a little obnoxious. I'm sick of watching my Magus roll a 1 during Spell Combat and getting slapped by enemies who are definitely not 10th-lvl Fighters and who definitely have not paid their feat tax for the privilege, especially at low levels.
Also, just want to say thanks for considering this feature! I think it very much fits the theme of your mod, but if you decide you don't want to implement it, please let me know and I may take a stab at it myself once I have more time.
