Converts all nearby poison into liquid flame, burning poisoned creatures from within. It also turns clouds of poison and mephitic gases into flame. The caster is not affected directly.

Ignite Poison is a level 3 Fire/Transmutation/Poison spell which causes all nearby poisoned creatures and poisonous clouds to burst into flames.

Effect

All poison and mephitic clouds in caster's line of sight are replaced with flame clouds. All poisoned monsters in line of sight take damage and lose their poisoned status. Higher spell power may increase the duration of the flame clouds and the damage taken by poisoned creatures.

Poisoned creatures take direct damage according to how many poison stacks they have, dealing approximately 200%-300% of the potential poison damage immediately, depending on spell power.

Duration of the flame clouds is 3 + (1d(20 + <power>) - 1) / 10 turns—that is, from 3-5 turns to 3-15 turns.

Strategy

Ignite Poison deals unavoidable heavy fire damage to every poisoned creature in sight. Combine it with ways of applying poison to multiple enemies at once, such as Olgreb's Toxic Radiance, for a powerful crowd-clearing tool. Or use it to ignite the poison clouds breathed by a Swamp dragon or Golden dragon to fry all the other monsters standing inside.

• Ignite Poison works great when used together with Mephitic Cloud; the noxious clouds generated by the former spell turn into clouds of fire. First confuse them with Mephitic Cloud, possibly casting it a few times to cover a larger area, then (once the monsters are confused) cast Ignite Poison and let the monsters stumble through the flames.

• Also note that monsters which are immune to Mephitic Cloud will happily walk through its noxious clouds to reach you. If you cast Ignite Poison at the right moment you can blast them as well.

• Some monsters may not want to walk into a cloud of fire if they are not yet standing in a cloud. Any cloud will do: steam (from zapping a wand of flame over water), poison (from casting poisonous vapours), etc.

• Few monsters are immune to poison AND fire. Using ignite poison, you can kill undeads, early phantoms and all the other nasties that are a real pain early on for a Venom Mage.

History

• Prior to 0.18, Salamander mystics had Localized Ignite Poison in their spellset.
• Prior to 0.17, Ignite Poison was a level-5 spell, but affected monsters with poison-branded attacks, chunks, and potions of poison. It did not use the Poison Magic school.
• Prior to 0.8, Ignite Poison used to be an amazingly painful way to eliminate poison from one's own system.
