Title: It baffles me the first time it has happened to me. Why the skill that should turn off reflect shields gets countered by what it supposed to negate.
Description:
In the official, dark claw damage doesn't get reflected when used on max pain or reflect shield. I know, I could've used it preemptively, but for some bosses, max pain is an insta-cast.
Why is this a good idea?
In my opinion, it's not a necessary change that needs to be quickly adressed since bosses melt so quick these days with BiS. But in the future, if Muh is planning for a custom dungeon with a challenging boss and include max pain in its skill list, it would be more convenient to not have it reflected, so in a party play we don't have to wait out bosses' max pain if SX failed to call out the skill or dark claw is still on a cooldown. Instead we can just go in, dark claw, then continue the fight.
What risks or downsides does it have?
Nothing. Just making it more accurate to the official.
