I’m currently building up a Level 20 Warlock to have the absolute maximum static damage (by static, I mean damage not reliant on a roll) on a melee attack.
A level 20 Hexblade Warlock with a 20 in Charisma can have the following additions:
- +5 from 20 Cha
- +5: Lifedrinker (Charisma-based)
- +6: Hexblade’s Curse (proficiency bonus)
- +10: Great Weapon Master
- +3: Magic Weapon
This totals +29 Damage.
Outside of using Tomes to increase my Charisma or getting the Legendary Item that increases Proficiency Bonus by 1, are there any other methods to increase flat damage that I don’t know of?
Please do not factor Dice or Dice Rolls into the modifier damage.
The answer doesn't have to be for a Hexblade Warlock; that's just the way I found to add the highest static bonus to a damage roll.

Aasimar Zealot Barbarian(16)/Grave Cleric (2)/Hexblade Warlock(1)/Any(1): +122 on one attack, +61 on later
Our character is an (Protector or Fallen) Aasimar level 16 Zealot Barbarian, level 2 Grave Cleric, level 1 Hexblade Warlock and has 1 level in anything, with the Great Weapon Master and Charger feats armed with a +3 heavy weapon.
Protector and Fallen Aasimars (Volo's) have a transformation ability (1 minute) which includes:
A 16th level Barbarian gets +4 to damage as part of the rage.
Path of the Zealot (Xanathar's) gets:
We use the Grave Domain's Channel Divinity: Path to the Grave:
And Hexblade's Curse:
Great Weapon Master lets us take -5 penalty to the attack roll to get +10 to the damage.
The Charger feat is a bit convoluted but in short; we get +5 to damage when using Dash, running 10 feet at someone, and use our bonus action to attack the creature.
The procedure:
Because we have multiple feature which use bonus actions, some set up is required:
Turn 1: Rage as bonus action and use action for something (e.g. Attack)
Turn 2: Curse the creature and use action for something (see last turn)
Turn 3: Activate Aasimar transformation as BA and use action for Path to the Grave. (Rage does not end as we have Persistent Rage)
Turn 4: Take the Dash action, move 10 feet towards an enemy, use bonus action to make a melee attack (par Charger feat). Choose to use Great Weapon Master on the attack.
As Path to the Grave only lasts a for one hit, we get one like this and later turns with half.
The calculation:
$$(5+3+10+5+20+8+4+6)\times2=61\times2=122$$
We can use a Belt of Storm Giant Strength to boost our Strength to 29 giving and additional +8 and/or a Ioun stone of Mastery for an additional +2.
