The Welter

With him spawn 8? eggs, which hatch to produce Spawns of the Welter, which do very minor damage but heal every monster around it (including The Welter) for massive amounts.

Attacks in melee range. A the welter never retreats.

When the eggs create the spawns, the blockers should use Challenge on them and lure them away from the boss. Be careful when luring away because if you get trapped by them the only way out is to have someone come take them off of you - the spawns will heal themselves and all other monsters around them, you cannot reasonably expect to kill your way out of a trap.

Make sure all spawns are lured away from the boss and that they will not roam around. If a spawn roams and finds you killing the boss, they will heal it back to full health very quickly.

Once the spawns are away from the boss, focus all your firepower on it.

It is soloable by luring the spawns away from the boss. However, due to the difficulty of that and the chance of spawns roaming to you, it is strongly recommend you bring a group.
