Even with the -Potion effect, this spell is strong enough to take the challenge out of entire sections of Crawl. Especially if you combine it with a backup spell for cold resistances, like [[Iron Shot]] or [[Orb of Destruction]]. Every time you cast Ozocubu's Refrigeration, you will be doing about 30 damage to every monster in your line of sight. Teleported inside Elf:3's final vault? 4 OR casts later, it is mostly empty. A room full of [[Boggart]]s? Easy. Vaults:5? At least you'll freeze all the guards and [[vault warden]]s.

This spell is a room-wide spell, that, ironically, also works well at taking at single targets. It has full range and never misses, making it good as an alternative to/combined with [[Freezing Cloud]].  
 
 
Even against single monsters, OR is a decent spell: it never misses. After 4 casts, most regular monsters will be dead. If you factor in the miss rate of the other level 5+ spells, few will take fewer casts.
 
  
However, -Potion ''is'' a very relevant effect. In tough encounters, make sure to quaff [[potion of brilliance|brilliance]] and/or [[haste]] before you start casting. Try to stay on staircases (more than usual), as that avenue of retreat is unaffected by the spell.

Ozocubu's Refrigeration (OR) is a level 7 Ice Magic spell which chills all targets within your line of sight (including invisible targets), dealing moderate cold damage. This is entirely unavoidable, has a 50% chance of slowing cold blooded targets, and does not always awaken sleeping monsters. However, damage is reduced when creatures (player or monster) are directly adjacent to each other:[1]

  • One adjacent creature: 66% damage
  • Two or more adjacent creatures: 33% damage

Strategy

This spell is a room-wide spell, that, ironically, also works well at taking at single targets. It has full range and never misses, making it good as an alternative to/combined with Freezing Cloud.

Against a large group that's widely spaced, you'll be doing about 30 damage to every monster in your line of sight.Teleported inside Elf:3's final vault? 4 OR casts later, it is mostly empty. A room full of Boggarts? Easy. The penalty is harsh, but you'll still be able to filter out weaker monsters after multiple casts.

Synergies and not so

  • Ozocubu's Refrigeration combines very well with Summon Ice Beast and Simulacrum, who are both cold-immune.
  • Any way to regain magic points that does not require quaffing a potion helps a lot. The passive abilities of Vehumet and TSO shine, but Sif Muna's channel ability is also not to be sneezed at.
  • A Lightning spire or Spellforged Servitor will not turn hostile when you freeze it, though the former may well get killed by a single application of OR.
  • Stay away from Animate Dead. Zombies are only cold-resistant and will turn hostile when you cast OR. And then, depending on the monsters you raised, it may cost you several more OR casts to put your former zombie army to rest again.
    • The same issue likely applies to all other summons and followers. So... if you plan to become an Ice Mage of Ru, then sacrificing Love is little love lost.

Quality of Life improvements

The screen will flash blue every time you cast OR. Over time, that may seriously reduce the joy of using this spell. Fortunately, there is a setting you can add to your .rc file that will block all players animations (not just of OR...):

use_animations -= player

Monster Version

The version of the spell used by monsters functions in much the same way, but has no effect on potions.

The following enemies cast Ozocubu's Refrigeration:
