best background for warlock 5e - An Overview
Strangely adequate, I recommend the forest gnome more than the rock gnome. Forest gnomes gain +one Dexterity, which I would value above the rock gnome's +1 Structure bonus. Also, the rock gnome's Tinker ability Regrettably does lots of items the artificer currently receives to try and do and also the ability (however flavorful) is sadly squandered.
