I made a level 2 paladin and received 2 level 1 spell slots. Ok cool. I then multi-classed to a 4th level Eldritch Knight. I gained 4 levels in EK but I only received 1 additional level 1 spell slot? I should have 3 level 1 spell slots for being a level 4 EK alone. I "lost" my 2 level 1 spell slots for 2nd level paladin? Why do spell slots not "stack" like they should? I should have 5 level 1 spell slots right now. I have half that. Yes I know Paladin and EK are both "half" casters. That doesn't mean I should lose spell slots for multi-classing. Or does it and I'm just ignorant? I'm not very familiar with 5th edition D&D but I know in previous version this didn't happen. You keep what you earn for every level/every class regardless of multi-classing or not.
