Statius's warhammer

Statius's warhammer is a weapon exclusive to Deadman seasonals, requiring 78 Attack to wield. It is part of Statius's equipment, a set of Ancient Warriors' equipment, and is dropped by any monster found in the Wilderness as part of a global loot table, the chance being relative to the combat level of the monster.

Special attack
Statius's warhammer has a special attack, Smash, that consumes 35% of the player's special attack energy and deals between 25% and 125% of the user's max hit, while lowering the target's current Defence level by 30% on a hit other than zero (the hit has to deal damage - even if it is a successful hit but rolls a zero, it does not work).

Defence level reductions do stack over multiple successful hits; each reduction is calculated from the current temporary level (so follow-up drains reduce fewer levels). Two successful special attacks thus reduce an opponent's Defence by a total of 51%.

Trivia

 * Ancient Warriors' equipment were originally added in a 2008, a year after the backup of Old School RuneScape.
