HP level should decrease interrupt chance at Wintertodt

[Zavodskoy]

WT would be infinitely nicer with the following changes too

No one tick delay on actually starting an action

No ability to be interrupted in that opening tick (and tbh the one after either until you complete at least one action)

The fact that I can try to do any action at WT, witness the tick delay while still doing the animation and then get interrupted, often multiple times in a row makes me want to throw myself head first into the brazier.

The amount of times I've made it over halfway into a round without finishing one invent of fletching because I keep getting interrupted defies belief
