Do damage and heal in same time....spell<<<

[R1DL3R]

I got one idea i see it on sc-fi move i think or never mine...its like some wizard put some relic one one spot and that relic do AoE dmg and heal,its take like example 0.5% of enemy hp and heal in that same radius own army.Example if there is a 10 enemy soilders and here 4 soilders 1 "wizard" it will take 0,5%/s hp * 10 = 5% it will heal that amount...if somone have any idea for name or how to start with triggers let me know...its like maybe aoe hp drain and aoe heal but 2 things in same time lot of triggers....
