Voice from the Past (1/Day). The professor can cast the contact other plane spell to contact a long-dead spirit, using Intelligence as the spellcasting ability.
Multiattack. The professor makes two Repelling Burst attacks. It can also use Force Barrier, if available.
Repelling Burst. Melee Spell Attack: +7 to hit, reach 30 ft., one target. Hit: 13 (2d8 + 4) force damage. If the target is a Large or smaller creature, it must succeed on a DC 15 Strength saving throw or be pushed up to 10 feet directly away from the professor and become restrained until the start of professor's next turn.
Force Barrier (Recharge 5–6). The professor magically creates a wall of translucent, golden force within 90 feet of itself. The wall lasts for 1 minute or until the professor uses this action again. The barrier can be a vertical or horizontal plane up to 30 feet on a side or a 10-foot-radius hemispherical dome with a floor. The wall provides 3. It has AC 17, 30 hit points, and immunity to poison and psychic damage.
Arcane Stasis (2/Day). When a creature the professor can see within 60 feet of it casts a spell, the professor can magically lock the casting in the moment before completion. The spellcaster must succeed on a DC 15 saving throw using the spell's spellcasting ability, or the spell fails and is wasted.
