Traits

Innate Spellcasting (1/Day)

The helashruu can innately cast gate, requiring no material components. Its innate spellcasting ability is Charisma.

Actions

Dimensional Hop

3/day

The helashruu can transport itself to a different plane of existence. This works like the plane shift spell, except the helashruu can affect only itself and can't use this action to banish an unwilling creature to another plane.

Multiattack

The helashruu uses Trap Life if it can. It then makes four shard whip attacks.

Reflect Energy

Recharge 5–6

The helashruu releases stored energy in a 60-foot cone. Each creature in that area must make a DC 18 Dexterity saving throw, taking 35 (10d6) damage of the most recent type dealt to the helashruu on a failed save, or half as much damage on a successful one. If the helashruu hasn't taken damage within the past 1 minute, the damage type is force.

Shard Whip

+10 to hit, reach 15 ft (4.6 m). Hit: 3d6+5 slashing damage.

Melee Weapon Attack: +10 to hit, reach 15 ft., one target. Hit: 15 (3d6 + 5) slashing damage.

Teleport

The helashruu magically teleports, along with any equipment it is wearing or carrying, up to 120 feet to an unoccupied space it can see.

Trap Life

Recharge 6

One creature of the helashruu's choice that is within 30 feet of the helashruu and that can see it must succeed on a DC 18 Wisdom saving throw or be trapped inside the helashruu's mirror. While trapped, the target is blinded and restrained, it has total cover against attacks and other effects outside the helashruu, and it takes 21 (6d6) force damage at the start of each of the helashruu's turns. The helashruu can have only one creature trapped at a time. A fragmented caricature of the trapped creature appears on the helashruu's surface while a creature is trapped inside it.

If the helashruu takes 30 or more bludgeoning or thunder damage on a single turn, the helashruu must succeed on a DC 15 Constitution saving throw or release the creature, which falls prone in a space within 10 feet of the helashruu. If the helashruu dies, a trapped creature is immediately released into a space within 10 feet of the helashruu.

GM Tips: Using Helashruu

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.
