Upon defeating him, Worldbreaker utters a few words before vanishing.

Strategy
Only one thing to say: Prepare to die! Considered the hardest of the part 2 super bosses for good reason. Like his counterpart, Judgement, Worldbreaker is immune to all elemental/physical damage, making only slayer/no element/chaos element skills the only way to damage him. Now, if you came here from Judgement, you might think "Sure! Seems easy, all I need to do is drain his mana to prevent the dispel and watch him waste turns!". Well... the problem here is that the number of spells that can be prevented using mana drain is 2, unlike the 6 of Judgment. Then you might think "Ok! Ill just use the Waning Moon Dance to null the damage!" Nope! None of Worldbreakers attacks are physical, all are auto hit, so also toss evading any of it out the window. Your next thought would be "Then, Ill use deflectors and Divine Destiny (+ 2 actions a turn) to survive!". Welp, like Marcellus/Labyrinth of Chaos, Worldbreaker also has an attack that both: Dispels AND goes though deflectors."This is complete BS!" will be your final thoughts as Worldbreaker crushes your team.

Now with that out of the way, lets talk a bit more about Worldbreaker's 4 main annoying attacks. First of all, they all buff him after using them while also damaging you, which alone makes these attacks the top of the BS list. But, each of the 4 attacks are used for different purposes. Sylph is based around reliable damage: Hers is the only attack that ALWAYS does full damage, but it only hits once. Gnome hits the entire party 3 times, which is fatal for any squishy people as super hide + super appear cant redirect the damage away from them. Undine is precise: It hits a single person 6 times, pretty much killing the person there. Salamander is more wild, randomly striking everyone on the team. With good luck, its possible to survive Undine and Salamander and only lose one person, and these skills have a 5 turn cooldown. The trick to this fight is buffing your team when Sylph and Gnome are down, as these are the skills that will end a party, with their AoE attacks. The other 2 attacks also hit the entire party, but only once, and can be blocked with deflectors. (Of course, this is taking into account that you drained his mana beforehand, so you don't need to worry about a daystar.)

With some extreme luck (Mostly hoping that on the turn you attack/turns spent buffing, Sylph isn't used, or Gnome, or he doesn't instagib the DPS with Undine/Salamander….) and lots of Legendary LoC gear (Or not, if you are ready to sacrifice your first born to RNGesus) you too, can defeat Worldbreaker!
