How Toughness works?
Steal+c+d+backstab combo? Or just backstab? Screenshot? The biggest backstab I’ve taken with 2999 armor was under 5k.
If you’re not playing to win, don’t complain when you lose.
There are skills and the Protection boon that decrease incoming damage. There’s Vitality that makes incoming damage less devastating, and it seems to be better than Thoughness.
Thoughness is added to defense. Damage of power attacks is calculated as random weapon damage * skill power modifier and is futher multiplied by (attacker power/defender defense). The listed damage is based on 2600 defense. Non-weapon skills have a fixed value for the weapon damage.
On a high-hp class, 768 thoughness increases effective health vs power attacks by a little over 22%(if the base is 2600, the effectiveness is much better for medium and light armor classes, approaching 33% in the former case), whereas vitality will increase effective health vs all damage by ~30%. Thoughness has a very slight edge in increasing effective healing as it makes each point of health worth more, but the effect is not as dramatic.
