Two known PHs: The first, just to the west of the king's hill (a single static wyvern between the hill and the river). The second, as a roamer who paths an area northeast of the king's hill (-2050, 740).

Deathleaper spawns just to the West of The Hill. The placeholder I know of for sure is the single static wyvern between the Hill and the river. The other static spawn near that location is a ph for King Rex.
Deathleaper has a real bad 2-tick AE DoT called Earsplitting Howl. It's so bad, in fact, that I have found it nearly impossible to box this mob. Mercs die in two ticks and a merc cleric has no capability for curing. I have seen a group with a mage pet tank kill this mob easily, though, as the AE range is only 75 feet. So Deathleaper is probably an easy mob for a ranged group and a really tough mob for a group that has to fight him up close.
