Oo that's lots of tags

Also the main draw with multiclassing Warlock into Barbarian is using the non-concentration armor spells like Armor of Agathys while raging, and taking advantage of the Warlock's utility while my rages are down. It also helps that the Fiend's level 1 ability has really nice synergy with the Barbarian's Reckless Attack.

EDIT:

That said, I'm actually looking more into a Paladin/Warlock now due to its synergy. Just to clarify though, so the earliest entry to multiclassing is at level 4, or could I enter my second class at level 3?
