Clicker (TLOU)

Critical Vulnerability. If the Clicker is hit by an critical hit attack, the Clicker becomes stunned until the end of its next turn and gains -1 bonus to its AC.

Keen Hearing. The Clicker has advantage on Wisdom (Perception) checks that rely on hearing.

Echolocation. Any creature that moves at full speed within 30ft of the Clicker must make a contested Dexterity (Stealth) check vs. the Clicker's Wisdom (Perception) check. On a failure, the Clicker knows the targets location until the end of it's next turn, at witch point the Clicker loses vision if the target if more than 30 ft away.

Echolocation Flaw. The clicker can't use its blindsight while deafened.

Fungal Fortitude. If damage reduces the Clicker to 0 hit points, it must make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is necrotic or from a critical hit. On a success, the Clicker drops to 1 hit point instead.

Devour Prey. The Clicker may only use its bite attack if the target's speed is reduced to 0 by any means, such as being grappled, paralyzed, or incapacitated.

Pack Tactics. The creature has advantage on an attack roll against a creature if at least one of its allies is within 5 feet of the creature and the ally isn't incapacitated.

Death Spores. When the Clicker dies, the fungi in it body starts to spread along the floor, walls, or ceiling that the body is touching. After 1 hour of the death of the Clicker, it starts to spread yellow/orange spores. If a creature breathes the spores, the creature has the effect of the Infection trait.

Infection. If the Clicker succeeds its bite bite attack on a creature, that creature becomes Infected. The condition lasts until the effected creature, is cast with lessor restoration (or similar magic), or some other antidote is found or made. Until the end of the condition, the effected creature must repeat a DC 10 saving throw every 24 hours. Upon 3 failures, the creature succumbs and becomes a Runner (Lesser Infected.) Successes do not end this effect or the condition.

Mindless: The creature is Immune to Fear and Charmed effects.

Multiattack. The Clicker makes two attacks, only one of which may be a Bite. A Bite can only be used on a creature that is already grappled.

Triggered Dash. If the clicker becomes aware of a creature's presence or hears a sound, it may use its reaction to move up to its speed and make one Thrash attack against the creature or sound source.

Unnerving Shriek. The Clicker can let out an unnerving shriek of clicking sounds in order to detect other creatures within 30 ft. All enemies within 30 ft of the creature must make a DC 10 CON save or be deafened for one round. Creatures that succumb to the deafened condition must additionally make a DC 13 CON saving throw or be stunned for 1 round as the shriek fills your mind with otherworldly dread.
