Chaos Spawn (Elder)

Spellcasting. The Chaos Spawn Elder is a 9th-level spellcaster. Its spellcasting ability is Intelligence (spell save DC 14, +6 to hit with spell attacks) and has the following wizard spells prepared:
• Cantrips (at will): fire bolt, light, mage hand, prestidigitation
• 1st level (4 slots): detect magic, mage armor, magic missile, shield
• 2nd level (3 slots): misty step, suggestion
• 3rd level (3 slots): counterspell, fireball
• 4th level (3 slots): greater invisibility, ice storm
• 5th level (1 slot): cone of cold

Magic Resistance. The Elder has advantage on saving throws against all spells except Radiant.

Overload. If the Chaos Spawn Elder gets within 30 feet of another Chaos Spawn elder, each of the Elder's within the range must make a DC 15 Intelligence saving throw. On a failure, the Elder takes 14 (2d6+8) damage and is stunned until the end of its next turn. On success, the Elder takes half the damage.

Sightless Glare. The Chaos Spawn Elder targets one creature it can see within 30 feet of it. The target must make a DC 15 Wisdom saving throw. On a failure, the target is paralyzed until the Elder deals damage to it or until the end of the Elder's next turn. When the paralysis ends, the target is frightened of the Elder for 1 minute. The frightened target can repeat the saving throw at the end of each of its turns, with disadvantage if it can see the Chaos Spawn Elder, ending the frightened condition on itself on a success.

Servitude. The Chaos Spawn Elder targets one  [Tooltip Not Found] within 60 feet of it and transforms the target into a [Tooltip Not Found]. If the target has not already performed its action this turn it loses its full action until next round.

Negate. Recharge: 4 (1d4+2) The Elder can use the Counterspell spell without expending a spell slot. Use this ability as if it were using a 3rd level spell slot.
