It's an old system from back when EverQuest had an XP penalty from dying to the point that you could loose levels, put in by a man who thought three minions should be a hard challenge.
I was referring to how radiation works with scourge. I know sets that have rains and other DoT effects tend to work better with scourge.
The problem with -def is it tends to only be good at low levels before everyone had 95%+ hit chance.
Since radiation blast seems to only have -def for the most part, is it any good?
What pairs best with it? I plan on pairing it with force field, but I am not sure if it works well with scourge or would be better on a defender.
