⟜ Requires Affliction

Tweaked from 5eYou already know this as 5e Slow — This is Slow reskinned as a Force power -- same AC/Dex penalty, no reactions, one-action-or-bonus, single-attack, and spell-fizzle d20 -- except the speed reduction is delivered as 1 'slowed level' (SW5e's slowed condition) instead of flatly halving your speed.
Afflict up to six creatures in a 40-foot cube: slowed, -2 AC and Dex saves, reactions lost, limited to one action or bonus action per turn.

Choose up to six creatures of your choice in a 40-foot cube within range. Each target must succeed on a Constitution saving throw or be affected by this power for the duration.

An affected target gains 1 slowed level, it takes a -2 penalty to AC and Dexterity saving throws, and it can't use reactions. On its turn, it can use either an action or a bonus action, not both. Regardless of the creature's abilities or items, it can't make more than one melee or ranged attack during its turn.

If the creature attempts to cast a power with a casting time of 1 action, roll a d20. On an 11 or higher, the power doesn't take effect until the creature's next turn, and the creature must use its action on that turn to complete the power. If it can't, the power is wasted.

A creature affected by this power makes another Constitution saving throw at the end of its turn. On a successful save, the effect ends for it.
