Efficiency gives the ambusher a bonus for kills in a row. For example, if you maim successfully then you gain an adrenaline rush which increases your precision and speed. It builds on itself until you gain a maximum bonus or lose all stamina. It also will give the bonus of giving a greater chance to hit the same place if you missed on an ambush, so say you wanted to hit the chest and got the left leg. The next ambush will have a nice modifier to hit the left leg again if you aim for it. The idea is that we get 'hot streaks' of kills and the excitement increases the efficiency of the spree. This lends to the next skill Killing Spree which is activated after 5 straight kills in the same ambush area.

Example for Efficiency: Rank 1 Second kill in a row same ambush area = +15 AS for one swing and a 15% rise in crit rank if hitting the same area Rank 2 +30 AS for one swing and a 30% rise in crit rank of same area Rank 3 +50 AS with 50% rise/weighting effect Rank 4 +50 AS with 50% weighting effect and -1 RT to Ambush for 1 swing and 50% weighting Rank 5 +50 with -2 RT to Ambushing and 50% weighting.

Hopefully this will give a really bloodthirsty routine for some assassins who like to rack up kills by lopping off heads, etc.

If 5 kills in a row and you are Mastered at Efficiency it sets of Killing Spree.


Killing Spree is a spell which gives you a 0 RT for 10 seconds when Ambushing and a running bonus of +50 to AS.
