So one of this question's To maximize a combo with True Strike, which is the most damaging spell with attack roll? answers got me curious. What is the maximum damage a 20th level character can do with a 9th level Magic Missile by the rules to a single target.
So my best I've been able to find is Aasimar or Goblin WLK 1/WIZ 19
- 9th Level slot (1D4+1)(11) [keep in mind you only roll once for
damage not 11 times] per
How many times do you roll damage for Magic Missile? - Empowered Evocation (+5)(11) (assuming 20 INT)
- Hexblade Curse (+6)(11) (Proficiency Bonus +6)
- Radiant Soul/Fury of the
Small +20 (Level 20 Aasimar/Goblin)
For a total of (D4+12)(11)+20 for (min-max)avg (163-196)179.5
Am I looking at this correctly? Are there other abilities out there that can increase this?
Feel free to include non legendary magic items. NO TOMES PLEASE
Only use things available on D&D Beyond please.
Acceptable books are :
- Basic Rules
- DMG, MM, PHB
- Sword Coast Adventure's Guide
- The Tortle Package
- Volo's Guide to Monsters

Maximum damage is 428
Here's how (I added some things to make the damage more consistent; average is 418.791):
The Cast
Your Character (let's call him Cody from now on) is a level 20 Goblin (ASs: 10/13/12/18/16/13) with these classes...
... who gets expeditious retreat and shield from his font of magic and carries these items:
Your Target (let's call her Tessa from now on) is a gas spore because of their exceptionally low Constitution and Wisdom. (although any creature that is not immune to disease or resistant/immune to force, cold, or necrotic is valid if they fail the saves)
The Process
The Calculation
f is force, n is necrotic, c is cold
This makes 391.804 force, 15.992 necrotic, and 10.995 cold damage for a total of 418.791 damage on average [Max: 428]
