The Welter

1. Spawns of the Welter healing him, and themselves with area spell (something like exura gran mas res). It is important to kill them first, or lure them out, and then attack the boss.
2. Do not let spawns to hatch - attack the eggs instantly when those appear!
3. Sometimes it is almost impossible to enter the cave safely, because of too many spawns. Instead of taking risk, good tactics is to go away for a couple of minutes (even further than one level above, so monsters will not sense you) and wait for spawns to dissapear.
4. Shrunken Head Necklace and Triple Bolt Crossbow are the rares that can be looted only from this boss.
5. If trapped, and surrounded by Spawns, do not waste your supplies. They will heal too fast to kill them alone. If noone can help you, make exit trick.
