Surprisingly(?) functional Monk Multiclass concepts

[Jakinbandw]

Warlock / Monk can be a great multiclass, but it's not, never, an immediate, obvious/brainless choice. The simple fact you need 13 CHA means you just cannot start with 16 in DEX, WIS and CON (for maximum optimization) or with 14 CON (avoid negative bonus). You'll have to make a choice, with the most obvious one being to sacrifice WIS because at least you get Mage Armor invocation for AC. It also means you'll crave for ASIs, especially the first one, and you'll never max both DEX and WIS.

You could go half elf and have something like:
Str: 8
Dex: 16
Con: 12
Int: 9
Wis: 16
Cha: 14

Not quite 14 con, but it's not too bad. And you have enough ASIs to take you to 20 in Dex and wis.
