OK! guys I tried that impossible missin again from save games and I unleashed a firewall 2 spell on them with some additional destruction points from top of the stairs and they were at the bottom too far away to detect me, but it was a vertical the spell still fried all of them.
I used firewall twice, and they are all dead. Not one of my guys is dead. lol mages are so overpowered, noi mage are OK, but warriors are underpowered seriously
