Reactions

Fist of Wind

When a creature the flying polyp can see targets it with an attack, the flying polyp can unleash a line of strong wind 60 feet long and 10 feet wide in the direction of the attacker. The wind lasts until the start of the flying polyp's next turn. Each creature in the wind when it appears or that starts its turn in the wind must succeed on a DC 17 Strength saving throw or be pushed 15 feet away from the flying polyp in a direction following the line. Any creature in the line treats all movement as difficult terrain.

GM Tips: Using Flying Polyp

3 tips available

When using Flying Polyp in your D&D 5e campaign, consider these tactical approaches:

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.
Telepathic Communication: This creature can communicate telepathically, making it excellent for coordination with allies. Silence spells won't stop its communication. Consider 'Mind Blank' or abilities that block telepathy.
Incorporeal Movement: This creature can pass through objects and walls! Use 'Magic Circle', 'Forcecage', or other magical barriers. Physical obstacles are ineffective.
