It is the sequel to Chaos: The Battle of Wizards and an ancestor of the popular X-COM series of games, also written by Julian Gollop.

These spells continue the theme from Chaos: The Battle of Wizards and include some of that game's more unusual elements (Gooey Blob, for example).

The aim of each level of the game is for a player's wizard to reach a portal which appears after a preset number of turns.

To do this, the player's wizard and creatures move around a map composed of square tiles, each of which represents one of various terrain types (for example, forest or the wall of a building).

An expansion pack was also available if purchased directly from Mythos Games which contained two further scenarios: "Islands of Iris" and "Tombs of the Undead", the latter being single-player only.
