If Overlord is attacked or if he makes another action, spell ends.   -Defend and Repair: The mech secures itself to the ground and erects metal plates around itself. Tiny little robots come out of little ports and start repairing the mech suit. While the plates are up, mech suit AC is 20. Until the start of his next turn, he heals 1d4+4 HP at the end of each round. If he is hit during this time, the repairs end and the plates retract, setting his AC back to normal.   Jetpack: Overlord blasts from the area to another area within 75 ft. Creatures underneath him within 5 ft make a DC 14 DEX save or take 1d4+4 fire dmg or DC 5 for half dmg.

Affected creature rolls DC 11 DEX check or takes 4d6 bludgeoning damage and is knocked prone.   The roof has a hole in it 2d6 ft wide, letting in a ray of sunlight. Any Unterdark creature starting their turn in the sunlight makes a DC 17 CON check or takes 7d6 light damage and is affected by Sunlight Intoxication for 3d4 minutes. Sunlight Intoxication causes disadvantage on all rolls and reduces INT score to 9 for the duration.

They make DC 12 CON check or are sickened.   -The strong presence of Salt can interfere with the mind.
