Boblin the Goblin

Evasion. If Boblin is subjected to an effect that allows him to make a Dexterity saving throw to take only half damage, he instead takes no damage on a success and only half damage on a failure.

Nimble Escape. Boblin can take the Disengage or Hide action as a bonus action on each of his turns.

Spellcasting. Boblin is a 20th-level spellcaster. His spellcasting ability is Intelligence (spell save DC 24, +16 to hit with spell attacks). Boblin has the following wizard spells prepared:

Cantrips (at will): mage hand, prestidigitation, shocking grasp, fire bolt

1st level (4 slots): shield, mage armor, expeditious retreat, chromatic orb

2nd level (3 slots): invisibility, misty step, mirror image

3rd level (3 slots): counterspell, dispel magic, fireball

4th level (3 slots): greater invisibility, polymorph

5th level (3 slots): cone of cold, telekinesis

6th level (2 slots): chain lightning, globe of invulnerability

7th level (2 slots): finger of death, plane shift

8th level (1 slot): dominate monster, power word stun

9th level (1 slot): wish

Legendary Resistance (5/Day). If Boblin fails a saving throw, he can choose to succeed instead.

Arcane Recovery (3/Day). Boblin can regain expended spell slots by spending 1 minute focused on the recovered spell level's spell scroll. He regains spell slots equal to his Intelligence modifier (5).

Multiattack. Boblin makes four attacks: two with his shortswords and two with his shocker.

Shortsword. Melee Weapon Attack: +15 to hit, reach 5 ft., one target. Hit: 13 (1d6 + 6) piercing damage.

Shocker. Melee Spell Attack: +16 to hit, reach 5 ft., one target. Hit: 44 (8d10) lightning damage.

Spell Scrolls (5/Day). Boblin can use an action to cast a spell from a spell scroll he possesses without needing to provide any material components. The spell level must be 9th level or lower, and the scroll is consumed in the casting.

Uncanny Dodge. When an attacker Boblin can see hits him with an attack, he can use his reaction to halve the attack's damage against him.

Counterspell. When Boblin sees a creature within 60 feet of him casting a spell, he can use his reaction to attempt to interrupt the casting. The creature must make a spellcasting ability check against DC 24. On a failure, the creature's spell fails, and the slot is wasted.

Boblin can take three legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. Boblin regains spent legendary actions at the start of his turn.

• Cantrip. Boblin casts a cantrip from his prepared list.
• Teleport. Boblin magically teleports up to 60 feet to an unoccupied space he can see.
• Arcane Barrage (Costs 3 Actions). Boblin releases a devastating surge of magical energy. All creatures within a 30-foot cone must make a DC 24 Dexterity saving throw, taking 60 (10d10) force damage on a failed save, or half as much on a successful one.
