The spellbook of freeze sphere is a deferred feature. It creates a tame freezing sphere which explodes at an enemy. It is included in SLASH'EM.


In SLASH'EM, the spellbook of freeze sphere is part of the starting equipment of the ice mage class. It is the staple attack spell for the ice mage in the early game, since the more powerful cone of cold begins out of reach. The ice mage starts with matter skill at basic level. As this skill improves, the number of freezing spheres summoned will increase to two at skilled and three at expert, all for the same casting cost.

General strategy

Since the freezing sphere does not attack a monster directionally in the way that force bolt or magic missile does, the ice mage must learn to manipulate the freezing sphere's position to defend against enemies. Using pet displacement is an important aspect; you will learn to dance through your spheres to get them into range of enemies. The ice mage should generally keep a freezing sphere floating around in the early game just in case. In the likely event that your spheres sometimes get left behind, they may go feral and revert to peacefully bobbing around in empty rooms. Tame freezing spheres do not appear able to turn hostile.

On the other hand, freezing spheres left to their own devices can cause a lot of problems. Since they are summoned monsters rather than pets, responsibility for their kills accrues to the player. This means not only that you will get the experience for the kills, but also the blame: shopkeepers, guards, peaceful monsters, and gods will direct their anger at you if your spheres blow up in the wrong direction. The ice mage thus needs to keep an eye on where his or her spheres go and make a point of using them only in safe contexts. It is usually unwise to attack mimics in shops with sphere attacks: they may miss their mark. The ice mage should use closed doors to control where spheres can travel and try to "burn off" excess spheres after a major battle before exploring the dungeon too far. (The fungi that crop up on a batch of corpses in SLASH'EM may be useful for this purpose.)

Finally, the ice mage must use caution while blind, since freezing spheres will not show up through telepathy and killing one by accident has the same anger effects as killing a pet.


A freezing sphere is the perfect weapon for jumping the distance between you and a cross-aligned unicorn. Two or three should do the trick.

Find a magic whistle early to keep your spheres close.

Keep in mind monsters' different vulnerabilities: freezing spheres will not affect the undead, nor, of course, ice vortices, etc.

Freezing spheres have the dramatic ability to take down shopkeepers without giving them the chance to leave their shop and attack. Simply stand diagonally next to an open shop door (not in front of it, as this allows the shopkeeper to kill you using ranged attacks) and keep summoning, using a combination of power surge and draw energy techniques as necessary. (You may need a pick-axe to carve out a suitable nook for yourself.) The shopkeeper will continue to switch weapons and patrol his or her shop interior, not sure if you are inside or outside. Eventually, you will stop hearing the explosions of your spheres (or you will level up). The shop is yours! This is something of an exploit, as the willingness of shopkeepers to sit in their shops and be repeatedly hit by spheres is likely unintentional.
