e.g. Renown I
Renown II
Renown III
Renown IV
Renown V <-------- Only grab this one, because this is how many "Arcane Coins" you can get daily. After you get you roll you follow this guild and this quest is timed.

I've seen many people asking about this roll, so here is an explanation on how to use it:

1) Renown - Mystic Loyalty Roll
2) Endeavor - Hardworking Sweat
3) Arcane Coins

1) Renown - Mystic Loyalty Roll
First I'll explain how to get the roll for those who don't know.
When your Renown is high enough, you can get a quest from Special Ops Agent in Sunstream, the quest is called "Renown X", this quest gives you Mystic Loyalty Roll X. (X is a number; 1,2,3... etc).

How can you get Renown?
Donate Provisions and/or Merit Incense to Alliance Master in Sunstream, your alliance will get Construction, and you get Renown.

How can you get Provisions and Merit Incense?
Provisions: They are dropped by mobs, or you can buy them from other players.
Merit Incense: You can get them by doing Mandatory Quests, and from Yasho Invasion event.

1000 renown - Mystic Loyalty Roll 1
??? renown - Mystic Loyalty Roll 2
??? renown - Mystic Loyalty Roll 3
7000(?) renown - Mystic Loyalty Roll 4
12000 renown - Mystic Loyalty Roll 5

2) Endeavor - Hardworking Sweat
After getting the roll go to Alliance Master and take Endeavor quest. This quest consists of 4 parts, 2 of them are random, and the other 2 are mandatory. The sequence of the parts is random; it changes everytime you do the quest.

This is a list of the available random parts:
(*) Kill Zaaras Outcast (10) (Spawn in Zaaras Platform, Sunstream)
(*) Kill Furious Moaner (20) (Spawn in Righteous Moaner, Sunstream)
(*) Kill Swiftedges Captain (Spawn in Moontop Hollow, Jadeon)
(*) Kill Poisonwing Bats (??? need to correct) (Cave of Fangs)
(*) Kill 2 types of mobs in jadeon (??? need to correct)

Mandatory parts:
You will be asked to dig a Summoning Stone in Jadeon (406 -113), but that stone is surrounded by some monkeys that will agro you, so take someone with you and let him/her lure the monkeys, and you dig the stone which will summon a boss in sunstream.
After that go to Sunstream (25 -167) and kill the boss [Greedy Gnarrlio (Yinsho Cottage, Sunstream, (25 -167))], it will drop some crafting mats and provisions, so pick them up and get ready for another part or to submit quest.

3) Arcane Coins
After finishing all parts of Endeavor quest, go back to Alliance Master and submit the quest, he will give you a Hardworking Sweat as a reward.
Now you have Mystic Loyalty Roll and Hardworking Sweat, so go to Special Ops Agent and exchange them for Arcane Coins. The amount of Arcane Coins depends on X (the number next to the roll and next to Renown quest) which depends on your Renown (the higher your Renown, the more coins you get).
