Mirror Blade

Gaudy fire spells have no place on my many mind-affecting-and-illusion-spells-only characters, but Green-Flame Blade is fun to use... what to do?

This mod contains a reskinned version of Green-Flame Blade, belonging to the Illusion school and dealing psychic damage, but otherwise as mechanically close to rules as written for the original as I thought made sense. (The "worth at least 1sp" restriction preventing use with Shadow Blade is often ignored and I'm not a fan of it myself, so made no attempt to replicate it.)

The attack is assisted by a temporary illusory duplicate, which will stay behind and wait for you to select the secondary target when applicable. Use the temporary spell to the right of the action bar when it appears.

Supports use as an Opportunity Attack reaction with the War Caster feat.

Pseudo-Spell Description

Mirror Blade

(The two halves of the spell are called Mirror Strike in game.)

Level: Cantrip

Casting Time: 1 Action

Range/Area: Self (5 ft)

Components: S, M (a melee weapon worth at least 1sp)

Duration: Instantaneous

School: Illusion

Attack/Save: Melee

Damage/Effect: Psychic (...)

Create an illusory duplicate of yourself to assist in a melee attack against a creature within 5 feet of you. On a hit, the target suffers the weapon attack’s normal effects, and you can cause the duplicate to strike a different creature of your choice that you can see within 5 feet of the initial target. The second creature takes psychic damage equal to your spellcasting ability modifier.

This spell’s damage increases when you reach certain levels. At 5th level, the melee attack deals an extra 1d8 psychic damage to the target on a hit, and the psychic damage to the second creature increases to 1d8 + your spellcasting ability modifier. Both damage rolls increase by 1d8 at 11th level (2d8 and 2d8) and 17th level (3d8 and 3d8).

Normally

To avoid causing conflicts with other mods, the spell is only added to class spell lists if Script Extender is used. When used, it's available to Arcane Tricksters, Bards, Eldritch Knights, High Elves, Sorcerers, Warlocks, Wizards, and via the Spell Sniper feat.

From Item

An old rapier imbued with the spell can be found in a Cartilaginous Chest in the room next to where Shadowheart is trapped in the tutorial. Any character can cast the spell while wielding the Mirror Blade weapon. Once they've successfully struck a second target, the spell is learned permanently so it can be used with a weapon of your choice.

You can summon a fresh copy of the chest using Tutorial Chest Summoning.
