Causes the caster to radiate toxic energy, continuously inflicting poison on everything in line of sight for as long as the spell lasts.

Olgreb's Toxic Radiance (OTR) is a level 4 Poison Magic spell which both damages and poisons any creatures without poison resistance in the caster's line of sight for a few turns.

Venom Mages start with this spell, though it can also be evoked using the artefact staff of Olgreb.

Useful Info

The damage can be split into two parts:

  • Impact damage. Olgreb's deals 1d(1 + pow/20) damage per 1.0 decaAut.[1] Ignores AC.
  • Poison status. Affected monsters have a 50% chance (on cast, and per 1.0 decaAut afterwards) to gain one poison "stack".[2] Monsters that are not poisoned yet have a 100% chance instead. Keep in mind that monsters have a limit of 4 stacks. See the Poison article for more detail on how poison stacks work.
Players hurt by OTR are affected differently; you'll take 2d3[3] damage worth of poison instead.

Creatures with poison resistance are completely immune to Olgreb's Toxic Radiance.

This spell has a duration of 1 + 1d(1 + pow/25) turns.[4] Casting this spell again will increase the duration; it does not increase the rate of poison or poison damage.

Strategy

Olgreb's Toxic Radiance is a great spell for crowd-control. It isn't fast, but it is good at thinning out a crowd; weakening the strong monsters and killing the chaff. Very effective in the Spider's Nest, as most insects and spiders are vulnerable to poison. Also great against evasive enemies in general, like bees and boggarts.

Works very well with Ignite Poison. Ignite Poison deals 200% - 300% of expected poison damage, immediately. This makes OTR becomes even better at dealing with crowds, able to wipe entire screens of monsters in just a few turns.

This spell can be useful even into Vaults and Depths, decent against monsters like vault guards and deep trolls. It struggles to remain relevant by the lategame, as OTR never increases in damage, and because more and more monsters resist poison. But, by then, a level 4 spell will have done its work.

Tips & Tricks

  • Olgreb's Toxic Radiance deals damage, so it breaks monsters out of fear, and dispels friendly summons that don't resist poison.
  • If there's only a single monster on the screen, it's better to use Poisonous Vapours instead.

History

  • Prior to 0.24 this spell did not deal direct damage on cast or properly trigger ally-harming conducts.
  • Prior to 0.19, the damage of this spell varied by distance and the spell also poisoned the player character.
  • Prior to 0.13, this spell poisoned all visible creatures for a single turn, didn't cause any direct damage. and could be cast when drawing the Venom card from a Deck of destruction.
  • In 0.10, the effectiveness of Olgreb's Toxic Radiance was modified to scale with spell power and to still affect poison-resistant players 10% of the time.
