Stalk

This spell makes the affected creature nearly invisible in rural surroundings (99% undetectable visually, as if hiding in shadows). The creature also becomes almost totally silent (as if moving silently with a 99% skill), and both its natural scent and its heat signature are masked by the spell (making infravisual or scent detection of the creature also 99% unlikely). A stationary creature under the effect of stalk is impossible to detect by nonmagical means at a range of greater than 10 yards.

Movement does not negate the spell, but it renders nonmagical detection possible by keen observation. In this case, the subject of the stalk spell still can move silently with a base 50% chance for success and remain visually and infravisually undetected with a base 65% chance for success; if the subject's normal hide in shadows or move silently skills are higher than these percentages, then they are used instead, although the infravisual masking percentage for a moving subject remains 65%. Scent masking is always at 99% for the duration of the spell.

The spell effect ends when the duration expires or when the subject attacks.

The material components are a piece of dried chameleon or lizard skin and the holy symbol of Mielikki.
