Guild Wars 2

Might
0.375 * Level + 5 = Power/Condition Damage per stack
i.e. at level 80, Might gives 35 power and 35 cond damage per stack

with my current gear setup and Pyromancer Puissance, I can get up to 15 stacks of might solo using staff (I have sigil of battle -might on attunement swapping- and rune of fire -longer might duration-)

you keep saying how it is rare for meteor shower to hit on same mob several times, it is also rare for eruption to keep hitting same mob in a row without them moving out of it

and I think surviving longest in dungeons involves —not getting hit-- (i.e. dodge, shield) more than toughening up (with 300 extra toughness) so u can withstand more hits

traiting 30 into fire enables you to get Pyromancer Puissance (getting 5 secs of Might every time you use a fire skill)
