Just a handy tip for turn 5. A perfectly timed cure 2 on death sentence(start casting when ds is 50%-70% casted), will result in the full cure 2 being applied after the ds hits. It's a great way to pop your tank up fast. Once you get the timing down you can even sometimes get a stoneskin to land right before the cast of ds followed by the cure 2 for maximum mitigation.

Another tip for when those ds's are poorly timed with conflags, is to sure cast a medica 2 during the fireball so that they land at almost the same time. This ensures that whoever goes in conflag won't die, and gives you time to focus on the tank for ds.
