I was trying out using invigorating pie instead of shielding pie to tank. That lead my into think, if spent skill points into intelligence, healing epic and the health regeneration epic I could increase the passive HP regeneration and the amount of HP I get from the rage epic one skill. I quickly realised that isn’t how those skills work or at least two of them so i did some testing. The only way to increase your passive health regen is with the Health Regeneration Epic which gives you 25 hp every 5 second and with a well fed buff that goes up to 45 hp every 5 second. Intelligence and the Healing epic has no effect on your passive health regeneration nor on the Rage Epic One.
Ok, so what does those two skill do?
Well, they increase the amount of Hp you get when you gulp down an Instant Healing Brew. Those two skill do not affect the healing brew just the instant ones. The health regeneration epic however does add 25 hp to the healing brew but has no effect on the instant ones. Tanking using invigorating pies without any of those skills, is still very good but if you want to heal more HP using lesser grade brews then spending points into intelligence and or even switching out Protection epic for healing epic is great as well. I actually like the fact that i cant passively heal health and i need to actively watch my Hp and use brews accordingly. I could have an active healing brew and use instant healing brew when i need to since instant brews don’t override active ones.
Here is the spreadsheet with all the values i got from testing ;
