Disruption is a special brand found only on the artefact great mace, Undeadhunter. Each time it strikes an undead target and deals damage dam, there is a 2/3 probability for the target to be blasted with disruptive energy up to an additional 300% damage. On average, you deal an extra +167% damage to undead targets.
Damage Calculation
Unlike most brands, bonus damage is not linearly distrubuted. Additional damage is calculated according to the formula:
random2avg((1 + (dam * 3)), 3))[1]
random2avg[2] takes the average of 3 rolls, here, which means the resulting extra damage approximates a normal distribution with a mean of 3/2 × dam[3] and a standard deviation of approximately 1/2 × dam[4].
Following the normal distrubution[5], additional damage dealt is between +100% and +200% damage, 68% of the time, and between +50% and +250% damage 95% of the time. (Assuming it deals extra damage at all)
History
- In 0.9, Disruption was made an exclusive brand to the Undeadhunter.
- Prior to 0.4, Disruption was a normal brand found on random melee weapons. Holy wrath was enhanced in its stead.

random2avgreturns an int, which shifts the mean slightly downwards from this value due to the effect of integer truncation for division in C++. - ↑ More exactly:
1/2 × sqrt[(dam × dam) + (dam / 3)]. The difference between the two calculations is negligible, as the increase is between 0.08 and 0.083(3) for anydamabove 1. - ↑ https://en.wikipedia.org/wiki/68%E2%80%9395%E2%80%9399.7_rule
