Sinister Strike

Sinister Strike (commonly abbreviated to SS) is a rogue combat ability, which all rogues start with at level 1. It deals normal weapon damage plus extra physical damage which scales with your level. You must have a melee weapon equipped to use the ability, and not be disarmed. Sinister Strike can be used on any mob, in any position, in any combat state, and has no refresh rate beyond its energy requirement. You must be facing your target.

It is recommended that you use a weapon with the highest average damage that you can attain for your main hand when using Sinister Strike, as the damage from Sinister Strike is calculated from a range between your weapon's minimum and maximum damage.
