Ranger 1 doesn't have the Spellcasting feature yet. Does the multiclassing rule still apply by RAW? #DnD

Multiclass spellcasting: a class doesn’t affect your number of multiclass spell slots unless you’ve reached the level in the class that gives you the Spellcasting feature. #DnD https://t.co/l5ISKAYDwp
