Lovelorn

A living creature bitten by a lovelorn must succeed at a Will saving throw or gain the fatigued condition and become unable to benefit from morale bonuses for 1d4+1 rounds. This is a mind-affecting emotion curse effect.

After 5 days, a lair claimed by a lovelorn grows cold, dark, and stale and causes unnatural, thorny vines to grow. This acts as a constant holographic terrain (Will DC 20) with a caster level equal to the lovelorn’s CR. Lovelorns typically use this ability to conceal entrances to their lairs, but also to make their domains appear depressing and grim. A lovelorn can maintain only one gloom at a time, and while within its gloom, the save DCs of the lovelorn’s spell-like abilities increases by 1.
