Jace Beleren

Mindmage's Insight. Jace Beleren is always under the effects of Detect Magic and Detect Thoughts.

Planeswalker. Once per short rest, Jace Beleren can cast Plane Shift targeting only himself, requiring no components.

Innate Spellcasting. Jace Beleren's innate spellcasting ability is Intelligence (spell save DC 18). He can innately cast the following spells, requiring no material components:

At will: Counterspell, Disguise Self, Dispel Magic, Invisibility, Mind Spike, Nondetection, Sending, Tasha's Mind Whip

3/day each: Greater Invisibility, Mislead, Modify Memory, Synaptic Static

1/day: Dominate Monster

Illusory Duplicate (Recharge 5-6). Jace Beleren creates a perfect illusory copy of himself that lasts for 1 minute, or until dispelled. This illusion appears in an unoccupied space that Jace Beleren can see within 30 feet of him. A duplicate's AC equals Jace’s. If an attack hits a duplicate, the duplicate is dispelled. A duplicate can be dispelled only by an attack that hits it, by a Dispel Magic versus Jace’s spell save DC, or when it is more than 120 ft. from Jace. It ignores all other damage and effects. As a bonus action on his turn, Jace can move each illusion up to 30 feet to a space he can see, but they must remain within 120 feet of him. For the duration, Jace Beleren can cast spells as though he were in an illusion’s space, but he must use his own senses to do so. 

Illusory Swap. As a reaction to taking damage, Jace Beleren can swap places with an Illusory Duplicate within 60 feet of him. If the damage dealt was from an attack, the duplicate takes that damage rather than Jace and is dispelled. Otherwise, there is no effect.
