Chronoctis, Beast of the West

Rift Rend. Melee Spell Attack: your spell attack modifier to hit, reach 5 ft., one target. Hit: $2d10+\text{PB}$ force damage. If this attack hits a target immediately after Chronoctis used its Shadow Lunge to appear near it, the target must succeed on a Wisdom saving throw or be unable to use its Reaction until the end of its next turn.

Temporal Snare (Recharge 5–6). Chronoctis distorts the flow of time around one creature it can see within 60 feet. The target must succeed on a Wisdom saving throw or be affected for 1 minute. An affected target's Speed is halved, and it has Disadvantage on its next attack roll. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Shadow Lunge. Chronoctis magically teleports up to 40 feet to an unoccupied space it can see. It must appear within 5 feet of another creature.
