Avoidance. If the Glassy guy is subjected to a saving throw, she takes half damage on a failed save and no damage on a successful save. Glassy also has a +20 bonus to all saving throws on top of her other bonuses.

Crit Armor. Glassy and her AC treats critical hits like normal attack rolls. She also treats her nat ones like normal attack rolls.

Discorporation. If Glassy drops to 0 hit points or dies, she is transported back to her glassy demiplane called the glassyness where she can’t leave it for 3d6 months. If during the first week of her being transported there she is killed again, then she is dead for 20d10 years before reviving.

Legendary Actions (∞/day). If Glassy fails a saving throw, she can choose to succeed instead.

no u. If Glassy takes damage, roll a d20. On a 1, she takes damage as normal. On a 2-9, nothing happens. On a 10-19, the source of the damage instead takes the damage. On a 20, the source of the damage takes double the damage.

Screw you specifically. Yes, YOU. If a homebrew character or monster specifically succeeds on a saving throw caused by Glassy, they fail anyways.

Spellcasting. Glassy’s spellcasting ability is Intelligence (spell save DC 35, +22 to hit with spell attacks). Glassy can cast the following spells:

At Will: all of them at level 9

Unyielding Nature. Glassy isn’t affected by things other than direct damage, meaning that any extra effects, including insta kills, do nothing to her. She can also function without air, drink, food or sleep, and she is immune to insta hit things like magic missile and the wish spell.

Multiattack. Glassy uses her Spellcasting. Then, she makes 5 Gun attacks and 2 Cannon attacks, or uses her nuke in place of the cannon attacks.

Gun. RangedWeapon Attack: +22 to hit, range 500/2000 ft., one target. Hit: 140 (20d12 + 10) gun damage.

Cannon. RangedWeapon Attack: +22 to hit, range 3000 ft., one target. Hit: 220 (20d20 + 10) cannon damage.

Nuke. Glassy shoots out a nuke to a place within five miles of her. The nuke arrives at that area after 1d4 rounds then detonates into a 1 mile sphere. Everything in that area except for Glassy must make DC 35 Con Saving throws. On a failure, the creature dies and is vaporized into dust, and can’t be brought back to life unless the wish spell is cast. On a success, the creature takes 315 (30d20) fire damage. If this damage reduces the creature to 0 hit points, it suffers the same effects as failing the saving throw.

Punching a god. In response to a deity or something like that insulting The Glass Cannon God, Glassy punches them really really hard, knocking their hp in half (or to one hp if the god has less than 500 hit points for whatever reason).

Glassy can take 10 legendary actions, choosing from the options below. You know how the rest of this stuff works.

Gun. Glassy makes a gun attack.

 Cannon (Costs 2 Actions). Glassy makes a cannon attack..

Nuke (Costs 3 Actions). Glassy uses Nuke.

Divine Fear (Costs 5 Actions). Glassy targets up to 10 celestials, dragons, fey, or fiends, in any combination within 300 ft of her. They must succeed on DC 45 Wis saving throws or be banished back to their home realms or to the astral plane if they are in their home realm. While banished, a creature can’t travel or communicate beyond the realm it’s been banished to. Every 10 years, a creature can repeat the saving throw, ending the effect on itself on a succes.
