Concussion

Version 0.34: This article is up to date for the latest stable release of Dungeon Crawl Stone Soup.

It pushes those it hits backwards, briefly stunning them in the process. If it pushes them into a solid feature, they will instead take an additional one-third of any damage that pierces their armour.

The concussion brand, exclusive to Maces & Flails, does the following:

Pushes monsters backwards and stuns them, with duration proportional to weapon delay to prevent stunlocks.
- If a monster is the primary target, the player will follow.^[1]
- If the monster is knocked into a solid feature, they take an extra 0-75% damage (avg. 37.5%) instead of being stunned.^[2]
Has no effect if there is another creature behind your target.

Sources

Concussion can only generate and exist on Maces & Flails. It is available through both random generation and through a scroll of brand weapon.

History

Concussion was introduced, along with the other weapon type specific brands, in 0.34.
