Paste the point onto your map. The placeholder has at least 6 spawn points in a radius around the intersection at this point. It took 6 spawns to get my robe. Used Bard Song of High Sun on each placeholder. If you sit at the point below, the placeholder will aggro regardless of which point it spawns at. Also confirmed a 12 minute spawn, not 18 minutes as posted elsewhere.

Killed it with my 62 enchanter and 55 wizard, with the chanter rune tanking while wizard burned it down. Hit for 348 when it broke through rune, didn't resist much. It is not level 50 as listed, it conned yellow at 55.
Jungle Hunter spawns at about pos 200, neg 400. PH is "a jungle stalker", and the spawn time is 18 minutes. This is visible from the wizard port in, so you can just camp there safely.
