Spiny

Version 0.17: This article may not be up to date for the latest stable release of Crawl.

Anything careless enough to attack a spiny creature in melee will take damage from the defender's spines. Ranged or reaching attacks ignore this counterattack, as do spells.

Monster Version

Each time anything attacks a spiny monster in melee, there is a chance that the attacker will take Nd4 damage (Nd3 if the attacker is a monster), where "N" is the defender's spiny degree. This damage ignores EV, but is reduced by random2(AC/2).

Player Version

You can acquire the spiny trait yourself by gaining the demonspawn spiny mutation. Spiny players may hurt attackers with a probability which depends on how many levels of the spiny mutation they have:

Spiny Damage
Spiny 1: 2d5
Spiny 2: 3d5
Spiny 3: 4d5

As with monster spines, this ignores EV. However, you can only affect the first attack of any given monster per round.
