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. Unfortunately, the cold freezes the contents of all potions in the area, rendering you unable to quaff anything for 7-15 turns.

Strategy
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 50 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. Vaults:5? At least you'll freeze all the guards and vault wardens.
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 brilliance and/or haste before you start casting. Try to stay on staircases (more than usual), as that avenue of retreat is uneffected by the spell.
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 will not turn hostile when you freeze it, but it may well get killed by a single application of OR.
- Stay away from Animate Skeleton and Animate Dead. These 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.
- Mummies can't drink potions at all, while Vine Stalkers cannot restore health with potions; both species can handle -Potion better as a result.
Quality of Life improvements
The screen will flash green 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.
