The Landslide Clause is a Nightmare Unique ring, hunted from The Mountain Sire in the Mortal Arena, always at item level 120. It is one of four Exceptional drops on its list — 2.5% of the Uniques that boss gives up, about 1 in 40 — and every kill rolls the list 5 times. It is built on Immaculate Ironvow Band — step 6 of the Ironvow Band line, item level 80 and up.

It always rolls the same numbers: +48 Armor, +36 Ward, +16% Stone Damage, +18% Ultimate Generation, +44% Stone Damage, +68% Ultimate Generation, +491 Maximum Health and +12% Power.

One Unique drop in 40 is a Mythical copy: the same item carrying 15–25% Mythical Energy that boosts every stat on it and can never be changed; the 15% floor is 10 times as common as the perfect 25%.

On top of that it carries The Landslide Clause — Your Ultimate is attuned to Stone, spreads 40% wider and buries foes in Crumble; Sunder erupts in a Seismic shockwave, but you move 10% slower.

It leans into Stone and Crumble.
