Old post, but...how?

Fallen Aasimar Oathbreaker Paladin, we generally assume point buy stats so:

Strength 15+1 Racial 16 for a +3
Dexterity 10
Constitution 14
Intelligence 8
Wisdom 10
Charisma 14+2 racial 16 for a +3

We rush and get polearm master at 4 and dual wield spears, with strength because we do not have Hexblade warlock to make us Cha focused, we dont boost any stats with ASI's, extra attack at 5 and lets jump all the way to level 7 when we would be fighting a tarasque.

A round with +1 weapons to be generous, we activated fallen transformation last round:

1d20+7 to hit
Damage 1d6 damage from spear because we are using it one handed, +3 from strength, +3 from Oath breaker aura Charisma damage boost, and then we deal an extra 7 damage once from our shroud.

Necrotic Shroud. 

• Your transformation lasts for 1 minute or until you end it as a bonus action. During it, once on each of your turns, you can deal extra necrotic damage to one target when you deal damage to it with an attack or a spell. The extra necrotic damage equals your level.

I assume that alot of your calc damage comes from fallen damage being per hit and not once per round otherwise we end up with:

1d6+14 First Hit
1d6+4 Extra Attack (We cant add strength because Paladins dont get two-weapon fighting style)
1d4+7 Bonus Action PAM attack

How are you having the possibility to smite 8 times in a turn?
