Just a heads up that a full combat point reset item costs 1 loyalty point temporarily. And since last patch you can now get all hp skills from level 50 to 55 instread of 55 to 60.
So reset your skills then purchase the shit ton of HP skills! The end skill gives 2 free accuracy as well!​

Bonus Tip: Craft the 275 HP potions to increase your survivability. See here:
