Refine and Grade

Let's use some examples of how a refine goes:

How to refine a Moan of Corruption [1] (470204) :

Moan of Corruption
Grade	Refine	Description
No grade	Go from 0 to +9 using Etherium (1000331) . You can grade to D now.	Bring a lot of Etherium. It can take a lot to succeed. Also choose Speed Refine option from NPC Leona.
Grade D	Go from 0 to +10 using Etherium (1000331) . You can grade to C now.	Same as before.
Grade C	Go from 0 to +10 using Etherium (1000331) . Now you need 1 HD Etherium (1000335) and 4 Blacksmith's Blessing (6635) for each attempt to +11. You can also use MVP Equip Refine Hammer (50052) consuming 14 Blacksmith's Blessing (6635) for a safe +11. You can grade to B now.	You can choose whichever option you want to get to +11. Remember that if you choose HD Etherium, after 4 failed attempts the hammer option becomes cheaper.
Grade B	Same as Grade C process. You can grade to A now.	Same as Grade C process.
Grade A	Same as Grade C. When it's +11, you need 7 Blacksmith's Blessing (6635) for each attempt.	Here I say: use the MVP Equip Refine Hammer (50052) to get to +12. It's cheaper than relying on RNG luck.
