What the stats mean

Power

Each point: +1% damage and +1% healing, on everything you do: attacks, spells, bleeds and burns, heals, and the shields you put on friends (their size grows the same way). 50 Power is +50%.

Grit

Each point: +1% max health. 50 Grit on a level-10 Guardian is 545 health instead of 363.

Armour

Each point: 0.5% less damage from every enemy blow, added to your class's own armour. Armour never goes past 60%. A blow of 100 does 100 × (1 − your armour).

Edge

Each point: +0.5% chance to crit, added to your class's own. A critical hit does 2× the damage (some talents raise that). Only you and your crew crit; enemies never do.

Every 1% of crit chance past 50%: a Rogue's crits on bosses and elites hit 3% harder for each (Cold Blood). Past 80%, each 1% more also adds 1.6% to their Dagger Storm's cleave (35% of the blow, up to 67% at 100%). Every 1% past 40%: a Hunter's Heavy Shot, Quickdraw and Storm Net crits 2% harder (Steady Aim). In Bellows, a Firebrand's chance to crit becomes extra damage.

Tempo

Each point: +0.5% haste. Haste makes you fight faster:

• the auto-attack swings sooner (a 1.0 s swing at 40 Tempo comes every 0.83 s);
• wind-ups and cast bars are shorter, and so is the pause after a swing or a cast;
• channels run faster, ticks and all;
• the global cooldown is shorter (never under 0.75 s).

It does not shorten a power's own cooldown, and it doesn't make you run faster. Haste from powers and brews multiplies with it: the Shaman's Spring Tide (+30%), the Hunter's Dead Eye (+50%), the Firebrand's Bellows (+25%), a Storm Draught (+15%).
