Can Charm move something from Vilemaw's Lair?

Yes, you can target a unit in Vilemaw's Lair with Charm, but the effect depends on where you are trying to move it:

• To a different battlefield: Yes, Charm can successfully move a unit from Vilemaw's Lair to another battlefield (RiftJudge FAQ #5028).
• To a base: No, you cannot move a unit from Vilemaw's Lair to a base. Vilemaw's Lair contains a "can't" restriction ("Units can't move from here to base"), and in Riftbound, a "can't" restriction always overrides a "can" effect. If you attempt this, the spell will resolve, the unit will remain in the Lair, and the movement portion of the effect will fail (RiftJudge FAQ #9513, FAQ #8797).

Important Note: Even if the movement is prohibited (e.g., trying to move to a base), the unit remains a valid target for the spell (RiftJudge FAQ #5028, FAQ #5698).
