I'm working on making a monk character for a new 5e campaign. I'm pretty much done with the build, just have a question about a tweak I want to make. Right now I feel like the monk lacks in damage and I want to increase my damage, but I don't want to lose out a bunch on survivability.
Race: Hill Dwarf Monk (+2 Con, +1 Wis, Dwarven Toughness)
Class: Monk, Way of Long Death
Current Stats: Str: 10, Dex: 15, Con: 15, Int: 8, Wis: 16, Cha: 10.
Should I bring my constitution down from 15 to 12, and instead make my charisma 13, so I can multiclass into a warlock 1 level, for Hex and Eldritch Blast for range. Hex will allow me to add 1d6 damage per hit and with flurry of blows I can potentially get 4d6 damage at higher levels. Also eldritch blast provides a good ranged attack that scales at higher levels.
Is the damage gained through this method, worth the potential loss in health?
I am looking for better ways to improve damage for my monk. I know the monk class is meant to be played as attack and run, always on the move fighter, but I also want some higher damage.
This character is expected to got up to level 18-20 in the campaign.
