Codex: Spell Combinations

Codex Entry 242: Entropic Death
Perhaps the victims would say it makes no difference, since those afflicted by a Death Hex already know there is little hope of survival, but they should avoid a Death Cloud at all costs if they do not wish to hasten the process: Merely touching the edge of the cloud is enough to set off a deadly reaction that deals truly massive spirit damage to the subject of the hex.

Codex Entry 243: Paralysis Explosion
The magic power of a glyph derives from the purity of its shape. When two glyphs overlap and their lines become confused, particularly when the glyph's effects are directly opposed as with Glyph of paralysis and Glyph of Repulsion, the magic has no choice but to dissipate instantly and explosively, instantly paralysing all those nearby.

Codex Entry 254: Shockwave
An adventurer beset from all sides may find solace within the temporary confines of a Force Field spell, which temporarily protects aganist all damage. Since the spell also prohibits movement, however, the original situation will still persist once the spell fails. If a mage casts Crushing Prison atop the Force Field, the contradictory effects will result in a spectacular disintergration of both spells, generating a shockwave that harms all in the area except the original subject standing in the epicenter.

Codex Entry 255: Improved Drain
The victim of a Vulnerability Hex must be wary not only of damage from the elements, but also spellcasters who wish to sap life or mana to restore their own bodies. The spells Drain Life and Mana Drain are twice as effective in those circumstances.

Codex Entry 257: Nightmare
Creatures that are asleep are particularly suggestible, and thus ill-equipped to resist the spine-chilling effect of a Horror spell. The vivid nightmares that result inflict massive spirit damage, the shock killing many lesser creatures outright. Those unlucky enough to survive are certain to emerge from the ordeal in a state of fear.

Codex Entry 258: Shattering
A creature frozen or petrified by magic, as from the spells or Petrify or Cone of Cold, is in a vulnerable state, subject to shattering if excessive force is applied to just the right spot. A critical hit from any weapon may suffice, and the spells Stonefist and Crushing Prison have been known to achieve the effect as well.
