Heavily nerfs the damage of the blood boil rune instead of outright removing it

About The Pull Request

Heavily nerfs the damage value of the blood boil rune from 25 to 10.

Why It's Good For The Game

The blood boil rune is one of the only runes that forces cultists to work together. Which in and of itself is a good thing. The damage of the rune was just way too high which this PR is supposed to fix.

Seems incredibly weak requiring 3 cultists only to deal 30 damage, perhaps the value should be 15, so that it deals a total of 45 damage to anyone standing in its range fully.
