If you plan on using lots of [[Poison Magic]], The '''staff of Olgreb'''<ref>{{source ref|0.29.1|art-data.txt|254}}</ref> is an excellent find. Not only will it enhance your poisonous spells, the extra damage and high chance to poison can come in handy for fighting some of the nastier poison-resistant enemies.

Even if you don't want to use poison magic much, you may still wish to train a little Evocations to take advantage of the evocable ability.

Staff of olgreb.png the +9 staff of Olgreb

+9 staff

Enhances Poison Magic
Provides immunity to poison
May deal poison damage and poison in melee; damage partially pierces resistance
Provides an ability to cast Olgreb's Toxic Radiance

Mechanics

When striking an enemy, the staff of Olgreb has a chance to deal resistance-piercing poison damage based on Evocations:[1]

Activation Rate: Evocations × 10%
Extra Damage: 1d(Evocations × 1.875) - 1
30% of this damage is irresistible.
The target will be poisoned. This effect ignores poison resistance.

You can also use an ability to cast Olgreb's Toxic Radiance:[2]

OTR Success Rate: 100%
Spell Power: (1 + Evocations) × 5
Cost: 4 MP

Desirability

If you plan on using lots of Poison Magic, The staff of Olgreb[3] is an excellent find. Not only does it enhance poison spells, but the melee damage can be good (even against rPois enemies) if you train some Staves and Evocations.

Even for those without poison magic, it can be nice to have:

  • It can evoke Olgreb's Toxic Radiance. OTR is a devastatingly strong AOE spell for Dungeon, Orc, and Spider's Nest, and you can use it with 0 Evocations. While it takes up the weapon slot, you can always swap it in or out.
  • It is one of the few sources of poison immunity. In addition to all the benefits of rPois, it prevents the paralytic poison of hornets and jorogumo 100% of the time. When tackling Spider or Snake, some form of poison resistance is nice to have.

The staff will occasionally spawn in a special vault full of assorted poisonous enemies (bees, spiders, and snakes). This can be an excellent find early on, though attempting to reach the staff at the end without already having a source of poison resistance can be risky. Frozen Ramparts is quite effective here, since it ignores the high evasion such creatures tend to share, nothing in the vault resists cold (and it will slow the cold-blooded snakes), and the tight quarters will force multiple enemies to take damage each turn.

History

  • Prior to 0.28, the staff had a fail check for evoking Olgreb's Toxic Radiance (but only 5 Evocations skill was required to get 100% success rate). Also, OTR could be activated from the v menu, instead of being an ability.
  • Prior to 0.25, the staff of Olgreb had a chance to cast Venom Bolt as well as Olgreb's Toxic Radiance when evoked, and only had a resistance-piercing chance to inflict poison instead of dealing additional poison damage.
  • Prior to 0.19, its enchantment level was based on your skill with Poison Magic (Poison Magic/3).
  • Prior to 0.14, it only granted poison resistance instead of complete immunity.
