The giant rockslug is a superior variant of the rockslug. It has a chance of spawning after purchasing the unlock Bigger and Badder for 50 Slayer reward points from any Slayer master.

Unlike normal rockslugs, the giant rockslug has a flat armour value of 2, meaning that it will not take damage from attacks that deal that much or lower damage.

Drops

In addition to 100% drops and tertiary drops, superior slayer monsters will always roll 3 additional items, of which only 1 roll may be from the superior unique table. The other rolls are performed on the regular counterpart's table; their displayed drop chances represent a single roll.

Drop rates are estimated based on 341 samples from the Drop Rate Project, unless otherwise cited.

The average Giant rockslug kill is worth 69,825.03.
