Question about Spike damage.

Hey guys, I've been using Necro's Blood skills for quite some time now. I really like them 'cause their damage goes through everything (right?).

I have one simple question. Say I want to form a group of spike Necro, does Shadow Strike work? I know that it does double the damage when the target's health is above 50% but what if all 8 people use it at the exact same time?? When they click on the skill, the target's health is above 50% so does this mean that if all 8 people click at the same time, the damage for each Shadow Strike is doubled? Or the game checks whichever Shadow Strike hits first, second, and third and the rest only does half the dmg? I hope my question is not too complicated. lol

This is the same thing for Deathly Chill?

It doesnt check their health when you start casting the spell. It will check as each individual shadow strike hits that person. So if someone's truncheon has the 20% casting speed on hit and they hit theirs first. then player 2 hits. then player 3. by the 4th person's SS (barring no healing) the person should be under 50% health therfore not allowing you the extra dmg.

yeah, someone has to hit 1st, 2nd, 3rd etc.

Ok, I got it.
