| It deals significantly more damage against the undead. |
Disruption is a brand exclusive to Undeadhunter which does the following:
- Has a 2/3 chance to deal an average of about +150% damage (0 - 300%) to undead targets. That's an average of +100% damage per swing.
- Unlike other brands, the damage isn't distributed linearly. Instead, damage is equal to
3d(3 * dam + 1)/3 - 1.[1] This approximates a normal distribution with mean of roughly3/2 × dam,[2] and standard deviation of roughly1/2 × dam.[3]
Unlike the similar holy wrath brand, this brand can be wielded by the undead.
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.

random2avg(X, Y) is equivalent to Yd(X) / Y - see random.cc:327 (0.28.0) - ↑ Random2avg returns an int. Due to integer truncation in C++, the average damage is slightly lower than 3/2.
- ↑ More exactly, standard dev =
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.
- Following the normal distribution, 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).
