<p>The tactic depends on situation which you can see when you meet the boss. I mean that sometimes <strong>The Welter </strong><img alt="" src="https://tibiopedia.pl/images/static/monsters/the_welter.gif" style="height:64px; width:64px"> has spawned before few minutes and there is not many Spawns Of The Welter - in this case i suggest to kill Spawns as first and then focus on the boss, but kill his Eggs at the same time (for mages the best way is to kill him with Thunderstorm runes, waves and UE). Just don't let the Eggs change into <strong>Spawn Of The Welter</strong> <img alt="" src="https://tibiopedia.pl/images/static/monsters/spawn_of_the_welter.gif" style="height:64px; width:64px">and kill it before it happen.</p><p>If you meet The Welter with a lot of Spawns firstly you have to <strong>lure the boss away from group of Spawns</strong> and then kill it in the same way as I mentioned.</p><p><strong>I don't reccomend recommend trapping with The Welter</strong>, it is the best way to commit a suicide or kill other players. If you are trapped with boss and some spawns, he can create Eggs out of your reach and make more spawns. In time there are so many of then them, that boss become almost immortal and sooner or later you'll be out of your supplies.</p>
