Chaos Mace

The uridimmu’s attacks with its mace are magical. When the uridimmu hits with its mace, the mace deals an extra 4d8 fire, lightning, or radiant damage (included in the attack). The uridimmu chooses the type of damage when making the attack.

Heroic Aura

Each friendly creature within 20 feet of the uridimmu can’t be charmed or frightened. In addition, when a friendly creature within 20 feet of the uridimmu makes an attack roll or a saving throw, it can roll a d4 and add the result to the attack roll or saving throw. The uridimmu’s aura doesn’t work in the area of an antimagic field spell or while in a temple, shrine, or other structure dedicated to a chaotic deity.

Recharge 5–6

A frightened creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. Fiends have disadvantage on this saving throw.

GM Tips: Using Uridimmu

4 tips available

When using Uridimmu 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.
Fire Damage Mitigation: This creature deals fire damage. Advise players to have fire resistance ready or use water-based tactics. Consider environmental fire hazards that could backfire on the creature.
Lightning Damage Awareness: Lightning attacks often have long range and high speed. Advise players to use cover and avoid metal armor/weapons. Water surfaces amplify lightning damage - avoid fighting near water.
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.
