This spell bathes the caster's surroundings in a sickly green light, inflicting poison on everything in sight (including the caster).

Olgreb's Toxic Radiance is a level 4 Poison Magic spell which causes all visible creatures in your line of sight (including you!) to be subject to a poison attack. This spell will be more effective at high spell power. Having poison resistance is a commonsense necessity before learning this spell. The artifact Staff of Olgreb can be evoked to cast this spell as well.

This spell is not the crowd control nuke one might expect. Poison works best when stacked with repeated applications, so using this to directly kill whole groups of monsters would take ages and lots of mana. What this spell will do is thin out a mixed or partly-injured crowd, killing off weaker and hurt monsters while chipping away at the stronger ones. However, it does nuke bugs (they are all vulnerable to poison), which is very useful in the Spider's Nest.

This spell has no effect on creatures that are invisible or otherwise transparent, whether or not you yourself are able to see them; Olgreb's light will pass through them harmlessly.

History

In 0.10, the effectiveness of Olgreb's Toxic Radiance was modified to scale with spell power.

Also, with 0.10, Poison Resistance is only 90% effective, requiring the player to have some fallback preparation (cure potions, Cure Poison spell, etc.) should things go awry. An invisible player would still be invulnerable.
