Impossible, Mage - No unit loss.

[Quelthos]

At level 17 I went back and cleared the orc embassy. My army was 106 royal snakes, 34 evil beholders, 3 giants, 5 cyclops, and 73 inquisitors.

Round 1: Giants, cyclops, snakes in front. Opened with double geyser (level 3). Killed 3 unit troops, weakened most except for two stacks of 70+ goblins. Used beholder mind control to burn one of the large goblin stack's turn. Threw down Lina's orb to slow down traffic. Enemy cast slow on my snakes. Shaman put down a totem that I killed with the orb.

Round 2: Another geyser. Everything dead but a few orcs, 2 shaman, two stacks of 20-40 or so goblins. Put up a stone wall in front of my army. Enemy cast magic pole axe on my giants for low damage.

Round 3: Enemy cast magic pole axe, kills some inquisitors. They resurrected themselves and I cleaned up the rest.

An incredibly easy fight at that level.
