When struck by any attack that would normally damage the nilbog, it actually gains hit points equal to the damage the attack would have otherwise dealt. A nilbog gains any extra hit points above its normal total as temporary hit points, though it can never have more than twice its normal hit points. (Excess hit points are simply lost.). The nilbog can only be damaged through the use of curative magic and effects (cure light wounds and healing potions, for instance). Curative magic deals damage equal to the amount it would normally heal.
A nilbog constantly emanates an aura of confusion in a 20-foot-radius. A creature in the area must succeed on a DC 11 Will save or be affected as if by a confusion spell (caster level 4th). The save DC is Constitution-based.
Nilbogs are defined by class levels–they do not possess racial Hit Dice. Nilbogs have the following racial traits.
Environment temperate plains and underground
Organization gang (4-9), band (10-100 plus 100% noncombatants plus 1 3rd-level sergeant per 20 adults and 1 leader of 4th-6th level), warband (10-24 with worg mounts), or tribe (40-400 plus 100% noncombatants plus 1 3rd-level sergeant per 20 adults, 1 or 2 lieutenants of 4th or 5th level, 1 leader of 6th-8th level, 10-24 worgs, and 2-4 dire wolves)
The nilbog is a goblin afflicted with a strange space-time reversal disease known as Nilbogism. The disease appears to occur when overly heavy use of magic strains the fabric of the space-time continuum and leads to some very strange localized events. The disease only affects goblins and is not transmitted by them. Nilbogs resemble goblins in appearance and are indistinguishable from them.
The nilbog favors ambushes, dirty tricks, and overwhelming odds to a fair fight. It moves within range of a foe so as to affect the creature with its spatio-temporal reversal ability.
Nilbog leaders tend to be rogues or fighter/rogues. Nilbogs worship various goblin gods of evil and can choose two of the following domains: Chaos, Evil, and Trickery. Most nilbog spellcasters, however, are adepts. Nilbog adepts favor spells that fool or confuse enemies.
