Massache's Method

Massache's Method is an Inquisition perk in Dragon Age: Inquisition.

Information
Massache's Method increases the amount of experience gained for each enemy slain by 5%. This is not retroactive.

Uses
While not as large of a bonus as Codex-related perks, it will still provide a significant increase over the course of the game, particularly once you are consistently taking on lieutenant level or higher foes.

A foe worth 10 XP would be increased to 11 XP (rounded), where a foe worth 1000 XP would be worth 1050 XP.

Trivia

 * Likely a reference to The Book of Five Rings, by Japanese swordsman, Miyamoto Musashi.
