Utility scored 98. A solid, even key lands near 75.
Your C is mostly a tool gap, see the note below. You held Bone Shield 96.6% of a 27 minute key and a Blood Shield 67.1%, and neither counts toward the mitigation axis. The real thing to change is the kick. You pressed 18 times and landed 11, but not one of them on Lava Bolt, which is the cast that actually leaked, and 4 presses hit nothing casting.
How the grade was built
◆ = 75, a solid key% = its share of the grade. Survival and mechanics carry no share: they start at 100 and only take points off. "Not counted" parts are shown for context and do not move the grade.
Your deaths
3 kicks of 18 landed on a cast somebody else had already stopped. A kick order agreed before the pull turns those into stops.
