The Belt of Fire Giant Strength goes to Vaeringjar. Good Lord, can you imagine him rolling two natural 20s on a back stab? Say he rolls (2) 8s one for each hand on a Frost Giant. Here's the damage.
(8 + 13 x 2) = 42 damage (x4) 168 total EACH HAND. That's a maximum of 336 on a pair of natural 20s
Bare minimum with no natural 20s, but a successful backstab. Say he only rolls a 1 for damage for each hand.
(1 + 13) = 14 damage (x4) is 56 each hand for a bare minimum of 112 if both hands hit.
112-336 backstab damage means someone will be slinking around and one shotting plenty.
