Naturally wamura cocoons drop from wamura. There are two kinds that I have found thus far. Wamuracampa spawn in the depths of Halvung and check as Tough to my lvl 75 Rdm. Wamura Prince can be found on the Island on the left part of the map of Mt. Zhaylom and check as VT to my Rdm.
To get to the Wamura Prince you need to go through the Halvung Gates in Mt. Zhaylom. To open them you need a key item "cast metal plate" that can be obtained from a ??? that spawns randomly in the area outside of the two gates. To get to the wamura prince camp: head to halvung from bufflau thickets or wajarom woodlands and have someone in the party cast escape. This will put you in Mt. Zhaylom. Head to the Halvung gate at H-8. Proceed north and into the cave in G-7, Trolls agro sight so you will need invis after the gate.
Follow the left wall in the cave and you will emerge into an open area with wamura prince. If you continue to follow the left wall there is a zone to halvung, so this is a relatively safe camp. However most people prefer to go on to the island: Take the zone into halvung, this part of the zone is very small and you will only need invis as wamura do not agro but the bombs do. Proceed down the tunnel, across the bridge, and up the tunnel on the other side. You will zone back into Mt. Zhaylom. You are now in the premiere wamura prince camp. There are several that pop just above the tunnel in the open area, but as they link, pulling them into the tunnel is suggested. Also the dragon that pops up there agros sight, but the range is not very large.
As I said, these were VT at lvl 75, my merit staic had no trouble fighting these. I recomend Barfira and either a rdm or a brd for dispel, as these mobs have a move called "Heat Barrier" that will give them VERY powerfull blaze spikes and enfire. These effects were doing 50-60 dmg per hit. These mobs are very slow so, they can be slept and nuked without gravity. Myself and a lvl 75 blm were able to take one out in 3-4 spells each. They also have very low evasion, but they have an AoE blind/damage move that does impair accuracy to a noticable degree.
The drop rate on the cocoons is not very high. It does seem to be higher from the Wamura Prince than the Wamuracampa though. I strongly reccomend that you bring a thf or /thf if you intend to farm these. We managed to get 7 in about 3 hours and 10k exp, with a drg/thf and a new moon. Other times with no /thf and random moon phase we got 2-4 in the same amount of time. With a full party of lvl 75s we were still getting 100-150 exp and exp chains up to 4 or 5, so these could be a good alternative to the exp off of weapons in sky or moon if you can convince a party to make the journey.
Well, I hope this information is helpful and good luck with the farming =)
