Uniques/Main Hand/The Second Oath

The Second Oath is a Demon Unique greatsword with no boss attached: any drop at Threat 17 or higher can turn out to be it, and at that Threat 0.7% of what falls comes up Unique. It is built on Masterwork Oathbound Greatsword — step 5 of the Oathbound Greatsword line, item level 60 and up.

It always rolls the same numbers: +71 Power, −8% Attack Speed, +4% Melee Lifesteal, +48% Power, +-8% Attack Speed, +19% Power, +21% Melee Damage and +10% Attack Speed.

On top of that it carries The Second Oath — Your cleave lands twice and hits 2 more bodies each time, but winds up 20% slower.

It is Adventure Mode loot.

Wearing it hands you Heavy Cleave and Groundbreaker.

“Sworn once in anger, once more to be sure.”
