Failure results in a fizzled spell. Combat Casting feat adds +4 to this check. If an opponent threatens the mage, the pending AoO is negated if this check meets or exceeds a DC of 5 + spell level +  opponents attack bonus with the threatening weapon.For each additional opponent threatening the mage, increase the DC by +2.Mage Killer feat adds +4 to this DC for that opponent.A successfull AoO has a chance of disrupting the spell as with normal rules for being hit while casting.Hence, Fred facing off against Joe. Casting Lightning Bolt:Defensive check DC 18Opponent check DC 18Must roll at least a 10, 50% chance of pulling it off.If Joe was 10th level, and added another +1 to his weapon, the Defensive check remains the same, and the opponent check raises to 24. Meaning he needs a 16 or better to not get whapped, roughly 25% chance of pulling it off.If Fred was 10th level as well, the casting would be childs play, needing only a 3 or better, but back to 50% against Joe.This means higher level casters will tend to get the spell off, altho they may end up losing some blood over it when faced with an equally competant sword swinger. Concentration is still a good still to take, and both sides can spend feats to become better than usual.{and pure casters have an edge over ..umm..impure casters..that just sounds wrong <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=":)" title="Smile    :)"  data-smilie="1"data-shortname=":)" />}Fred: 5th level mage, INT 16 {+3}Joe: 5th level fighter, Str 16 {+3}, Weapon Focus, +1 weapon.eh? or maybe I am just out of my mind <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=":)" title="Smile    :)"  data-smilie="1"data-shortname=":)" /></blockquote>
