It's at the start of their turn. It's not like they got a chance to do anything. I didn't include multiple rounds.I've never really seen people do Searing Smite over divine smite, partially because half the damage comes on their turn. Like the Green Flame Blade damage, it is situational .... usually if the BBEG is right after you it will work and if he is not right after you it won't work nearly as often.
Also, it was crap in 2014, and it's less damage at spell level 1 and 2 (assuming 1 round).
Which doesn't have 5th level slots.I just finished a game with a 20th level 8 Warlock/10 Arcane Trickster/1 Paladin/1 Bard. The Paladin spells I used were Wrathful Smite and Divine Smite (but I was also playing with a 22 Charisma and an 8 Intelligence at games end).
Their warlock 4th level slots would deal a little more, and the Trickster would deal less. Average is probably about the same, and it's not worth getting both.
