To really reinforce how good the Monk is as an option: At level 2 you can use Flurry of Blows to make three attacks, dealing a total of 3d4+6d6+9 (avg. 37.5) damage (not accounting for accuracy). At level 5 that jumps to 14d6+16 (avg. 65). At just 1 Ki point for that small mountain of damage, that’s a pretty great turn 1. Way of Mercy can add another 1d6+3 (assuming 16 Wisdom), too. If you want to get extra crazy, add three levels of Assassin for the guaranteed critical hits against surprised enemies (I guess Sneak Attack is in there, too). At level 8, that’s 34d6+19 (avg. 138). Then to cap it off, add two levels of fighter to get Action Surge and make two more attacks on turn 1 for a total of 48d6+27 (avg. 195). The build has several challenges (no magic attacks, all melee so movement is an issue, no ASI at level 8) and it doesn’t account for accuracy, but the math is really fun, and an Eldritch Claw Tattoo will solve some of the bigger issues.

Monk 5 (Mercy) / Rogue 3 / Fighter 2 / Druid 2 (Spores) - 4 Attacks

Fighting Style could be Unarmed Fighting (1d8 instead of 1d6 or 1d4)

Eventually want Ki-Empowered Strikes (or Eldritch Claw Tattoo) for resistances...

If you can activate Spores and Eldritch Maul (Eldritch Claw Tattoo), it's 2d6 bonus damage per strike...
