Rogue's stolen power, Accursed Beam has been rebuilt to be more in line with other ranged powers in the game:
The mechanic of “bonus power for health” has been retained.
Base damage now uses a standard curve rather than being based off of maximum Health
Bonus damage percent is given based off of maximum Health.
The self damage no longer crits or brutals but is increased in magnitude, resulting in less spiky health loss.
Note that the damage % bonus from health is no longer reflected in the tooltip damage range, so perception will be worse than reality on initial viewing.
Overall a correct nerf to the power, but still very, very strong compared to other ranged powers.
