I just started this game 2 weeks ago.
Yeah, its little hard to get in party to clear dungeons for 'The dead refuse to die' for 200 draken orbs.
What I did is I camp in Celestial Basin to get my mystic badge for 15,000 peaches, then 23,000 peaches for Oath Necklace (8,000 peaches + 15,000 peaches trade for 50 orbs) and another 23,000 peaches for Eternity belt. During that time, I managed to collect a lot of chests for weapon upgrade materials. From this, I can upgrade my baleful to 11.
From here, I dont have problem to use LFP in F8 to clear all dungeon in 'The dead refuse to die' quest. But, please study all mech so you will make your party easier to clear those dungeons.
After get those 200 draken orbs, 'beginner guide' says it can trade those 200 draken orbs for legendary bracelet. I cannot find this, maybe this is old guide.
For bracelet, I have to clear 'Know Thine Enemy Part 2' to get the 5 pcs material to trade for unrefined bracelet at Mushin Tower. This quest is way too hard compared to 'The dead refuse to die' because the dungeons mech is really complicated, especially hollow's heart.
So I camp in Celestial Basin again for Destiny Ring (8,000 peaches+50 draken orbs) and managed to get materials for baleful 12 weapon.
Today, I cleared the quest. Luckily got very OP party. Really grateful get the chance to party with them. Now I got all the legendaries (even not end-game legendaries).
So for beginner, Celestial Basin does help a lot. All you need is little patient and courage. This is MMORPG, no short cut unless you spend for it.
