!IF you know how the Trogg mechanics work, just skip this!
During the General Umbriss encounter, a pair of troggs will spawn at around 1 minute into the fight, one of the Troggs is carrying a buff called Modgud's Malice, it is pretty easy to spot since the Trogg is bigger and has a purple-ish cloud around it.
This buff is a pretty big deal, since once the mob carrying it dies, it will explode giving anyone in the blast radius a debuff which ticks for 20k and slows for 25%, if it explodes near the boss it will buff him, increasing his damage by a 100%.
To completely counter this mechanic, just CC the trogg that has the debuff, and have it cc'd for the rest of the fight, this will stop any additional buffed troggs to spawn.
Just have your tank pick up the unbuffed troggs that spawn and cleave them down, making this fight a piece of cake.'
The original thought for this boss is to have people CC the buffed trogg, then killing it after killing the unbuffed ones, making people still need to struggle with the explosion.
AKA this is not intended, so don't even think about posting that it is.
TL;DR
1: CC the buffed Trogg
2: Kill the other adds as usual
3: Keep it CC'd for the rest of the fight.
