Immunities undead immunities
As a standard action, a marrowblight can leap up to 15 feet into an empty space, provoking attacks of opportunity as normal for this movement. Each creature in a square adjacent to the marrowblight at the end of its movement must succeed at a DC 15 Reflex saving throw or gain the off-target condition for 1 round. Creatures that fail this check by 10 or more are also knocked prone.
The marrowblight can exclude a number of allies from this effect equal to its Intelligence modifier (2 for most marrowblights).
Environment any ruins
Marrowblights are muscular undead monstrosities filled with hate. They typically arise from brawny humanoids that were exposed to strange radiation or arcane energy that painfully warped their flesh at the moments of demise, creating hideous bone spurs that protrude from the creatures’ backs, cheeks, jaws, and shoulders.
Marrowblights can use these spurs as weapons, as they drip with the disease that courses through the creature’s undead bones like marrow.
Scientifically advanced planets have pinpointed the biology-warping processes required to create marrowblights, and some elebrians have willingly succumbed to this horrific undead fate. Naturally occurring marrowblights still exist. These are typically among the universe’s most vicious and hateful undead, eschewing society and living creatures in particular. Sometimes, though, such marrowblights ally with forces that seek to assert and spread the superiority of undead creatures throughout the universe and beyond, including the Corpse Fleet and those who sympathize with the exiled navy.
Marrowblights are typically 8 to 10 feet tall—including the horrific bone spurs that protrude from their backs—and weigh upward of 300 pounds.
