Magic in combat is represented in one of the following ways:
Note that higher level spells take more time to cast. This is represented by a countdown preceding the descriptor, e.g., “3…2…1…STUN”. (This means that higher level spells are more susceptible to being disrupted.)
If a spell does not affect its target (e.g., if the target is affected by another spell that negates the first spell), the target announces “NO EFFECT”.
Spells cannot be stacked. If someone is under the effects of a spell, casting the same spell on them again has no further effect. Note that the player does not need to announce the fact that the spell was already affecting them. If the caster was unaware of the effect and ended up wasting a spell, so be it.
Touch spells using spell packets must be cast on a willing recipient. If the recipient is conscious and says “REFUSE” after the caster says the descriptor, the spell does not take effect and is wasted.
Touch spells may be cast on an unwilling recipient by using a wand or staff. (The rationale is that if the recipient is unwilling, the spell becomes a form of combat, which must use boffer weapons.) An attempt to cast a spell on someone using a wand or staff may be parried by a weapon or blocked by a shield, just like any other weapon attack.
