Traits

Enveloping Fog

The falsifier fog can occupy another creature’s space and vice versa, and the falsifier fog can move through any opening as narrow as 1 inch wide without squeezing. The fog’s space is lightly obscured, and a creature in the fog’s space has threequarters cover against attacks and other effects outside the fog.

False Appearance

While the falsifier fog hovers motionlessly, it is indistinguishable from ordinary fog.

Horrific Illusions

A creature that starts its turn in the falsifier fog’s space must succeed on a DC 13 Wisdom saving throw or be frightened until the start of its next turn, as it sees visions of its worst fears within the fog. While frightened, a creature’s speed is reduced to 0. If a creature fails the saving throw by 5 or more, it is afflicted with short-term madness.

Limited Telepathy

The falsifier fog can communicate telepathically with any creature in its space.

GM Tips: Using Falsifier Fog

2 tips available

Flight Control Strategy: Target flying creatures with spells like 'Hold Person', 'Web', or 'Grease' to ground them. Without flight restriction, they can escape melee range easily. Consider area denial spells below their flight altitude to force them into disadvantageous positions.
Cold Damage Strategy: Cold-based attacks can slow or freeze. Prepare 'Heat Metal' or fire spells as countermeasures. Ice terrain can be used to create difficult terrain for melee characters.
