1) I've tested harvesting lighting essence from a pine trees with or without LVL3 lightning essence boon with an iron axe. Haven't noticed any difference in quantity or quality of harvested essence. Is it working? Am I doing something wrong?
2) Having lvl1+lvl2+lvl3 essence boons in a tool will result in 60% increase of amount of harvested resources or only 30%?
3) Similar to previous question: if I put lvl1+lvl2+lvl3 lightning strike in my spellcast will it result in increased chance of invoking the lightning strike compared to a single lvl3 rune without lvl1+lvl2?
4) Another similar question: does spirit boon stacks in these cases?:
a) one piece of armor, lvl1+lvl2+lvl3 spirit boon
b) two pieces of armor having a lvl1 spirit boon each
5) Identical to q4 but with fire skin/fire nova/other similar spell?
