oh yeah add this bit of information about special refining NPC's in Eden group too.
coz some peepz in Thor don't know about them.
Normalson - uses normal Ori and Elu to upgrade, equipment may break when going over safety limits
Suhnmi - uses Enriched Ori and Elu to upgrade, equipment may break when going over safety limits, and uses Enriched Ore Rates (higher success rates)
Mighty Hammer - can use +7 certificates to get equipment up to +7 w/o breakage, he also uses HD ori and HD elu to upgrade equipment from +7 to +9, failures in upgrading using HD ore will make the item degrade 1 level, you can continue to upgrade as long as you have a corresponding HD ore in your inventory. success rates are the same as any refinement NPC, costs 20k zeny each upgrade attempt. He's one of the NPC's that can upgrade equipment from +9 to +10 using HD Ore, and can use safe to 10 certificates to protect the item from downgrading on failure.
Enriched Hammer - can use +7 certificates to get equipment up to +7 w/o breakage, he also uses Enriched ori and Enriched elu to upgrade equipment from +7 to +9, failures in upgrading using enriched ore will make the item degrade 1 level, you can continue to upgrade as long as you have a corresponding Enriched ore in your inventory, he uses Enriched Ore Success rates, costs 20k zeny each upgrade attempt. can also use safe to 10 Cert. to prevent breakage from failures when trying to upgrade from + 9 to +10
MRS Hammer - can use +7 certificates to get equipment up to +7 w/o breakage, he also uses Enriched ori and Enriched elu to upgrade equipment from +7 to +9, failures in upgrading using enriched ore will make the item degrade 1 level, you can continue to upgrade as long as you have a corresponding Enriched ore in your inventory, he uses Enriched Ore Success rates and does not use up any Zenny to upgrade.
