Do not treat these as interchangeable melee upgrades—they sit on different virtue lines and pact families. — Soulframe weapon comparison.
Rare Fey Long Blade requiring 19 Grace with Spirit co-attunement, 48 ATK, and 32 stagger. Farm three fragments through the Fort Kearnhold Siege, then forge it at Tuvalkane. Sinecure-errant Vella and the Mirifuir siege line offer alternate fragment sources.
Marrow's Bane is a Rare Long Blade cleaver requiring 21 Courage, forged from the claws of the great Vadagar Bear under Bromius's pact. With 54 base ATK, 40 stagger, and 5% smite, it is the highest stagger weapon among Courage cleavers in Preludes 15 — ideal for stun-locking bosses and exploiting charged attack windows. Farm 3 fragments from Vadagar Bear (a Bromius pact Omen beast encounter). Craft at Tuvalkane with Scrap Steel×15, Patch Leather×40, and Moranite×6. Purchase a copy from Wares of Zenith for 250 Arcs. Marrow's Bane is the endgame Courage cleaver that Stultin (53 ATK, 16 Courage) and Falx (54 ATK, 12 Courage) build toward. The five sharpened spires on the blade evoke the teeth of the Omen Bear itself, dripping with primal power. Pairs synergistically with Bromius pact abilities and Tethren melee bruiser builds that capitalize on 40 stagger for repeated knockdown loops. The lore describes it as a menacing cleaver wielded by the Arbearer Bromius, with a darkly humorous pact condition: protect the old roots yet to heal, or pick your teeth after a good meal. Essential for high-Courage builds targeting Omen beast graces and Neath'uns content.
