Martial Vigor

Martial Vigor is a passive talent, opening the Warlord (Red) tree.

In-game
This effect stacks with any other similar bonus, but is does not simply add the 4% per point to the total damage reduction, instead multiplying it (for instance, with 5 points, multiplying the total damage reduction by 1.2, i.e. turning 30% reduction into 36%). At low levels of Defense, its effect is negligible.
