Invisibility

Invisibility folds an object or willing creature out of ordinary perception. The target fades from sight while its sounds soften and its scent disappears. Equipment worn or carried when the spell is cast vanishes with the creature. An item removed from it becomes visible, and an item picked up later does not disappear.

Perceiving the Target

A creature that looks toward the target or receives another meaningful sign of its presence makes a Will Save against the spell DC, including the DC Bonus in the table. On a success, that observer perceives the target normally for the rest of the casting. The illusion remains intact for everyone else.

Sound and scent can prompt the same Save. Tracks, displaced water, opened doors, moving objects, and other physical evidence may grant a bonus or call for a prescribed chance under the normal rules for invisibility. Extraordinary senses and suitable magic can also reveal the target.

After remaining still for one full round, the target gains +2 Spell DC against detection. This bonus ends as soon as it moves or takes an action.

When casting the spell directly, the caster may designate one creature per point of Intelligence to perceive the target normally. A potion grants no such designation.

Offensive Actions

An undetected invisible attacker cannot be dodged or parried, and its attacks are automatic critical hits. Each attack or directly hostile spell counts toward the Offensive Actions limit in the table. The action that reaches the limit resolves while the target is still invisible; the spell ends immediately afterward.

A spell affecting several enemies counts as one offensive action. Movement, defense, healing, and other actions that do not directly harm or hinder another creature do not count. At Level 10, offensive actions never end the spell.
