The spellbook of poison blast, teaches the poison blast spell. It doesn't exist in vanilla, but in some variants.


Unskilled / basic

At unskilled or basic skill, poison blast generates a ray akin to the poison blast of a green dragon or iron golem; it deals (xplev/2+1)d6 damage to non-poison resistant targets. If the blast hits the player, it has a 1 in 15 chance of being deadly poison (instadeath) and a 1 in 3 chance of dealing dexterity damage.

Skilled / expert

At skilled and expert level, the spell may be targeted at a location no more than 10 squares away that is in sight and an open space. The explosion cannot be cast underwater or on the Plane of Water; if used while swallowed, it is automatically cast on your own location.

Two to nine explosions are generated; the first is centered at the target location, and subsequent explosions are randomly placed on any of the nine squares around that point (unless swallowed). Each explosion affects the surrounding squares as the unskilled/basic spell, with the exception that the player suffers only the damage and not the additional poisoning effects.


In SLASH'EM, the spellbook is a level 4 attack spell. As with all spells in SLASH'EM, skilled/expert will not change the cast type to explosions and the spell will always produce rays unless the sigil of tempest and sigil of control techniques are active.


In GruntHack it's a level 5 attack spell.
