NEED MULTI-HELP PLEASE

I need the G rank Akantor's bow for White Fatalis. It requires a Big Elder dragon jewel. I need to kill a G rank elder dragon, so I need Lao shans G rank LS. IT REQUIRES 3 LAO RUBIES! So, with my Akantor bow, I did the 8* Lao quest, I broke everything off, but failed, I NEED TO KILL IT, GET IT'S SWORD, KILL AN ELDER DRAGON GET THE G RANK VER OF AKANTOR BOW!!
DAMN!!!!!!!!!!!!!

The fastest way to get BEDJ is to kill chameleos with the fire DS Punishment blades and the ceanataur Z armor set. Skills: element attack up, sharpness +1, sharp sword, defense -40.

Drink a mega/power juice and just demondance his belly (just in front of his back legs) and after a while attack the tail to see if it comes off.

Best way to get rubies is to kill Grank Lao, I think his dropping rate of rubies is higher than the high rank one.

First, BED Jewel is easier with hunting Chameleos, in which fire dual will be the fastest option (forgot which one)

I believe you are talking about the Corpse Blades.

Help!
I can't find corpse blades or punishment blades!
Although they seem to look like twin flames, I'll try it out.
Edit: I need 5 Rathalos tails! ( 4 remaining ) it's really rare!

I got 2 Rath rubies ages ago, It's kinda hard getting tails, I'll tail run him, aaah the things I do for rare stuff. I killed 99 Rathalos in total. I can't wait for my new title
