Скачать или смотреть Toram Online - Refine 1 slot from 0 to +S

vblade personal refine guide (tested on 11 March 2023, works with 2s equipments):

Tech 255 + lv 10 all 4 refine smith tree char:
0 to 9: mithril ore
9 to D: mithril ore + anti-degradation
D to C: orichalcum ore + anti-degradation
C to B: orichalcum + super anti-degradation

Luck 255 + lv 1 refine char:
B to S: mithril ore + anti-degradation

note:
the equipments won't lost during refine, as long "magic hammer" is not being used
because of the refine pity point system, preferable to use mithril ore instead of hematite during refining from +B to +S
every refine (success or not) you get a point and every 150 points you get +1% flat increase in success
at start, use High Purity Mithril 24 points with Refinement Ticket (+9) to get to 216 pity pts
hematite can use up to +8
for a cheaper version (longer time):
i. 0 to C: Tech char using mithril ore
ii. C to S: Luck char using mithril ore

The Ore Value:
Hematite +1
Iron +2
High-purity Iron +6
Damascus Ore +2
Damascus Steel +4
High-purity Damascus +12
Mithril Ores +4
Mithril +8
High-purity Mithril +24
Ori Ores +8
Orichalcum +16
High-purity Orichalcum +48
