In order to do so, you must meet the ability score requirements for your current class AND the new one (most people forget or are unaware about that pesky little "and" 😄), as shown in the Multiclassing Prerequisites table.
Thanks for this. I only hope we are going to need this info for the full release!
I am new to multiclassing in 5e, though have been doing a bit of reading. I am not sure I’m correctly understanding the point about needing to meet the ability score requirements for my current class quoted above though. Does that mean that if, for example, I built a dexterity-based paladin who didn’t have 13 STR but had 14 CHA that I’d not then be able to multiclass into, say a Warlock? Or that I wouldn’t then be able to take further paladin levels after multiclassing?
