death sentence has a 35s recast time, although a phase transition can reset it as well, which is why peolpe often assume it has a random element.

I run a timer for DS, and I can make sure to have virus, eye, or ss active for every DS. For the very first on, on the pull, watch for the first plumet, then finish your cast to top off the tank, and put virus on twintania. She\\'ll DS before it wears off.

As a scholar, I also like to force the pet to heal the MT preemptively (use obey). You can macro or click it manually, but I prefer to macro it in with my adlo and physick.

For phase 2, if you time the transition to occur immediately after DS casts, you will line up conflags with death sentences, and your tank can step into conflag to avoid the hit and debuff. To do this, you must push the boss below 85% health during the DS cast.
