Thanks for all about the answers
I choose Paladin and now i have level 3, and when i may have more necrotic ability, spells i choose Spore Druid or maybe better is Great Old Warlock?
It is very inefficient to multiclass before hitting lvl 5 of Paladin, as you'd miss out of a Feat at 4th and the Extra Attack at 5th.
Paladin - warlock is definitely the more synergistic choice. You aren’t getting much out of making your Paladin also a Druid.
I know that I just droned on about effectiveness :), but a Spore Druid would be a nice continuation for an ex-Oath of Ancients Paladin.
