If you bring each Forest, Ice, Desert Titans you’ll have a 50-60% chance of defeating. Bring 4 Meks to combine into Mega Mek extra 20% since mega mek does decent damage. Couple DreadNaughts (ascendant saddles)on attack your target, 10-20 gigas(ascendant saddles)on aggressive. Beginning of fight be sure Titans and Dreads are placed close to where King spawns, Forest infront, Ice on the side, desert on opposite side of Ice. Create mega mek and whistle gigas to attack. On Megamek, get behind King and keep on hitting. The goal is for everything to knock the King onto his knees before he’s able to do his massive hit attack.
