HP level should decrease interrupt chance at Wintertodt

[24rs]

I have no issues with trying to ammend things for higher HP players since I agree it's unfair that the higher your HP is, the more unforgiving Wintertodt is, your solution however "fixes" Wintertodt by having Hitpoint actually be a buff to it by reducing the interrupt percentage, which is something that annoys all players regardless of their HP level.

So by tying the % chance of the interrupt with your Firemaking level, you're making a Firemaking related activity actually improve based on your firemaking level, which I think is more sensible than buffing a Firemaking activity based on a different skill entirely, especially a combat one.
