1337s's guide to Genkai vol.1 :-b
{Run Away!}
Now if you make it past that let me try to add some help.
I've done this quest more times then I'd like to think already. I've been with at least 10-15 people to get their G1 items and I'm only 58. >< I generally start with the Exo Mold just because of accessibility. It's VERY easy to get up to the secret room area and kill Exo's. I can duo this relatively easily with whoever needs the item.
The bomb ash. Have BST will travel. :-b If you have a BST friend you are GOLDEN on this one. Sic bats on bomb, watch bomb explode, thank bomb for ash. If you do not have a BST, have someone with Stun. A 73DRK fits this nicely.
Oh Eldieme. How I hate you so. However, I have gotten 5 papy's in 3 hours before. (I've also only gotten 1 in 3 hours too but we won't go there /angry Carnage. :-b). EVERYONE says go through Beaucadine blah blah blah. F that. :-) I zone to Batallia, hang a left, and pass the bone wall to the south. Go through there, take all lefts, and find the avatar gates (Titan's, Shiva's, etc) Here you will find 2x Lich and 1x Fallen Soldier.
Kill these and run North (sort of back the way you came but pass up the hall way.) This will take you through a big room with Ka's and some ghosts I think. Just sneak through here and, whatever you do, don't step on the squares. :-b This will take you to another area just like where you were. Again, 2x Lich, 1x Fallen Soldier.
You can keep going back and forth like this and GREATLY reduce down time.
Now for the "Tip of the Week". LoL. Many will say this is BS blah blah blah, but it has yet to fail me. If you need more than one Papy, ZONE AFTER EACH DROP! :-b With all the patches SE put on they reduce your chances of drops the longer you've been in the zone. This is how I was able to get 5 in 3 hours. We have tried with not zoning and got REALLY frustrated fighting for hours with nothing but bone chips and bruised knuckles to show for it. The trip through Beaucadine is a waste of time IMO. You could have killed 6-8 Lichs by then and already have your Papy.
Well I hope some of this helps and best of luck on the hunt. I still have an LS member that desperately needs it so if you want another 50PLD let me know. I'm having trouble making time for all our LS members and myself. LoL. I'm pretty set on closing in on 60 this weekend too.
