'''Ignite Poison''' is a level 4 [[Fire Magic|Fire]]/[[Alchemy]] spell which causes all nearby [[poisoned]] creatures and poisonous [[cloud]]s to burst into flames.

==Useful Info==
All poisoned monsters in line of sight take [[fire]] damage and lose their poisoned status.<ref>{{source ref|0.31.0|spl-damage.cc|2138}}</ref> All poisonous clouds and noxious fumes (i.e. mephitic clouds) in the caster's [[line of sight]] are replaced with flame clouds. Tiles affected by [[Eringya's Noxious Bog]] are not reverted and have a chance to create short-lived flame clouds.

Higher [[spell power]] increases the duration of the flame clouds and the damage taken by poisoned creatures.

*Poisoned creatures take direct damage according to how many [[Poison#Monster Formula|poison stacks]] they have, dealing approximately 200%-300% of the potential poison damage immediately, depending on spell power.<ref>{{source ref|0.30.0|spl-damage.cc|2095}}<br>Specifically, Ignite Poison deals <code>(Stacks * 2)</code>d<code>(12 + 6*pow/100)</code> damage. At maximum poison (4 stacks; "extremely poisoned"), this ranges from 8d12 to 8d18. Like poison damage, this spell ignores [[AC]].</ref>
*Duration of the flame clouds from poison and noxious clouds is <code>3 + (1d(20 + <power>) - 1) / 10</code> turns<ref>{{source ref|0.30.0|spl-damage.cc|2051}}</ref>—that is, from 3-5 turns to 3-15 turns.
**Duration of the flame clouds from Noxious Bog is instead <code>1 + 1d(1 + <power>/30)</code> turns (2-5 turns).<ref>{{source ref|0.30.0|spl-damage.cc|2013}}</ref>

Note that the spell can't affect monsters with fire immunity, e.g., [[lava snake]]s or [[salamander]]s. Casting the spell won't damage them, and they will retain their poison. It will still affect clouds under these monsters, however.

==Strategy==
Ignite Poison deals heavy, unavoidable fire damage to every poisoned creature in sight.

*With [[Poisonous Vapours]], it becomes a high damage, never missing attack which is more MP efficient than similar Conjurations.
*With [[Olgreb's Toxic Radiance]], it's strong against whole groups, able to attack the whole screen.
*With [[Mephitic Cloud]] and [[Alistair's Walking Alembic]], it will create flame clouds, which can damage those immune to poison.
*Particularly great with [[Eringya's Noxious Bog]], which inflicts high amounts of poison, even against those with poison resistance.

The biggest downside is that Ignite Poison relies on poison, making it worse against enemies with poison resistance. It is also somewhat poor with turn economy. Otherwise, Ignite Poison is a very strong spell, usable even in the late game.

===Tips & Tricks===
*It doesn't matter where the poison clouds come from, they'll be turned into fire. You can turn a [[swamp drake]]'s or [[swamp dragon]]'s breath against it. You can ignite clouds from a [[scroll of poison]] - just make sure you have no immediate plans to move anywhere. Can also convert clouds from a low-power [[condenser vane]].
*Ignite Poison doesn't count as a fiery beam; it doesn't create [[steam]] clouds on water, and it won't get rid of [[freezing vapour]]s.
*[[Vehumet]] considers this spell destructive; [[Alchemist]]s looking for this spell should consider worshipping this god.

==History==
*Prior to [[0.31]], Ignite Poison was a level 3 Fire / Poison / Transmutation spell.
*[[Venom Mage]]s started with this spell in [[0.25]] and [[0.26]].
*Prior to [[0.18]], Salamander mystics had [[Localized Ignite Poison]] in their spellset.
*Prior to [[0.17]], Ignite Poison was a level 5 Fire / Transmutation spell, but it also affected monsters with [[venom]]-branded attacks, poisonous [[chunk|flesh]], and [[potions of poison]].
*Prior to [[0.8]], Ignite Poison used to be an amazingly painful way to eliminate poison from one's own system.
