Was camping Nomala spawn on a 45 ranger and decided to go solo the only xp-able(light blue) cons on track while waiting, the undead troll and erudite sailors(there are 4 of these, underwater) the undead erudite sailors despawn like a merchant on death, but are not merchants(in fact, they even gave loot once... but no xp). The undead troll sailors in the same area gave xp as normal.
