Main question: does arterial cut count as a dot so that hand of purity blocks 70% of the damage?
Also some other general holy questions for this fight:
1) what last talent do you use? I feel executioners sentence would be good due to the heavy tank damage, but also holy prism? due to durumu's large hitbox.
2)glyph of flash of light? due to having to use it to top up tanks quickly for arterial cut?
3) can a clemency specced holy pal make this a 1 tank fight due to rolling hand of protection on the tank, or are even 2 bops not enough
