Guild Wars 2

Does anyone know how much damage reduction (percent) a Signet of Earth gives at level 80? I know it gives 180 Toughness, but I can’t seem to find the percentage anywhere, and the damage reduction formulas I’ve looked over confuuuuuse me.

Thanks in advance!

Umm Sigil of Earth does not give any toughness it is offensive sigil that stack bleeding on critical strike.
Only sigil that stacks toughness is Sigil of Momentum but it gives only 25 * 5 toughness on exotic version.

He meant the utility skill.
Not sure how much it gives because numbers change higher you are level.

Oops, I meant Signet! Thanks, edited topic.

Well to achieve 50% damage reduction you need to increase you armor twice.
So 180 toughness on elementalist with basic armor 1836 (exotics) give more damage reduction that to character with 2500 armor.
Formula for calulating that looks like (your armor + bonus toughness) / 1836.
This formula tells how much more damage reduction you have from lowest armor.
Modifying it to (your armor + bonus tougness) / your armor will give you percenteg increase of bonus armor.

Thank you very much! That was explained well.

Doesnt make any sense, if toughness is the same as armor, why have it as two separate stats, because thats the way you explained it.

Armor = Toughness + Defense
Toughness comes from the Attribute value
Defense comes from the Gear values

Well toughness increase armor (statistic) and armor is sum of toughness and defense.
Defense change very little this statistic only exist on armor (item).
Toughness on the other hand can vary much, you can put it on items as statistic, get it from traits, food, etc.
That is why I used term as bonus toughness becouse you can’t have bonus defense.
Toughness and armor (statistic) are often used as same thing.
