Well the Basin wiki is down (again) so I can't confirm it, but iirc a bolt's damage is [mlvl/2]*2-1.
Rocky Waste its area level is 75, so then a bolt would deal [75/2]*2-1=73. No clue if these bolts are increased by the P#, but if they are, then it should be 125%, so 91.25 per bolt. Then after 75 lightning resistance it would be ~22.8125 per bolt.
And you took
1,738 damage in a
single frame.
Where did all that damage come from?
War Cry is a nova-like skill after all and it shoots out a massive amount of missiles, so I figured maybe all those dozens of War Cry missiles that "hit" the Scarab all triggered a bolt.
Well, just a though..
Anyway, excuse the nerd talk, rip mr Singer :<
