So, am not sure if that question is really stupid or am just ovethinking..
Lets say you have high vengeance atm, ur health is 90% for example, will using Expell harm grant u more dmg than using jab? Expell harm does 50% of the amount it heals as nature dmg, does that counts for the overheal also?
For Juggernaut hc i just glyphed Guard and went diffuse magic, Guard on first breath , DM on 2nd and Guard again on third. Felt more safe this way, just kept spamming Expell harm as taking the bombs.
