Sangromancer question

Quote from knightlance13 >>

ok so here is the sequence for this I think...

1:  My turn I cast blood bond on a fighter.

2: The fighters turn is normal because the smite is a bonus action I take.

3:  My next turn, I activate Wilting Smite on the fighter using my bonus action, I can then throw a cantrip/move if i want as a normal action.

4: The fighter then uses the smite on their turn.

 From my understanding, that's correct.

Basically, while only one of the spells require Concentration, both require a spell slot so they can't be cast on the same turn.
