The Shadow Wyrm is a superior variant of the wyrm. It has a chance of spawning after purchasing the unlock Bigger and Badder for 150 Slayer reward points from any Slayer master. Shadow Wyrms cannot be safespotted like regular wyrms in the slayer only area, but Protect from Magic will prevent all damage while at range.
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 estimated based on 847,282 kills from the Drop Rate Project, unless otherwise cited.
The average Shadow Wyrm kill is worth 78,326.69.
The average Shadow Wyrm kill while on a Konar task is worth 80,496.19.
