Manifold Fetter

Description

Lingering Chain (always on). When a creature ends or escapes a crowd-control effect that you imposed (examples: charmed, frightened, grappled by your spell, paralyzed, restrained, stunned, or its speed was reduced to 0 by your spell), its speed is reduced by 10 feet.

If the effect ends on its turn, apply the –10 ft immediately and it lasts until the end of its next turn.

If the effect ends off its turn, the –10 ft applies on its next turn and lasts until that turn ends.

Stacks with difficult terrain and other speed penalties; doesn’t stack with itself from this item.

Double Chain (PB/day). Proficiency bonus times per long rest, when you cast a single-target cantrip that targets one creature (e.g., eldritch blast with all beams directed at one target, chill touch, mind sliver, toll the dead), you can have spectral chains lash to one additional creature:

The second target must be within 10 feet of the original target, within the cantrip’s range, and otherwise be a valid target.

Make separate attack rolls or saving throws as appropriate; resolve damage/effects separately.

This does not change the cantrip’s action economy or create extra beams beyond normal.

Rulings & Examples (quick)

If Lemara paralyzes an enemy with hold person and it succeeds on a save at the start of its turn, it immediately gets –10 ft speed for the rest of that turn (after the condition drops).

If an enemy escapes web on someone else’s turn (or the spell is dispelled), the –10 ft applies on the creature’s next turn.

Double Chain: Lemara casts mind sliver on an ogre; she also targets the goblin standing 5 ft from the ogre. Both are within 60 ft of her—legal.
