Ok guys, best setup for skill critical damage path should be something like this, at least from my understanding, wich is always improving:
+8/+10 R110 light set. (10 % skill cooldown) + 5% Skill Power(Light set bonus) vs 5% P.Skill critical damage(Heavy set bonus).
+5 Radiant Warrior circlet ( +10 P.Skill critical damage, +7% Patk, +5% P.Skill Power,+50 Attribute,+5 STR)
Lv2 Heir Radiance PVE/PVP (Stats + Patk and later PVE/PVP dmg)
+5 Dragon Rind Leather Shirt(Stats + Pdef + 3% Cooldown)
Dragon Slasher (30% P.Skill critical damage + 30% P.Skill critical rate +500 Attribute + Patk)
+5 Superior Brooch (stats + Patk trigger)
Greater Ruby, Greater Red Cat's Eye, Greater Aquamarine(cooldown), Greater Opal, Greater Emerald,+ 1 G tanzanite/G Diamond etc, opal can be 5 and you can change Emerald too but the 1st 3 and opal 5 are essencial.
+5 superior Kaliel Bracelet ( stats +7% patk/pdef/mdef) or +11 Lucien's Bracelet(event) (+10% Patk)
Insanity, Sayha(8+), Venir 12+, High-grade talisman Skill cooldown(30days), High-grade talisman Skill Power(30days), High-grade talisman Attribute attack(30days), endgame get Heavenly and epic talismans. Abundace 4 is good for PVP or Raids in PVE but item skill isn’t stackable with Sayha taliman.
+5 Seed Bracelet lv 4 (Patk, 5 slots)
+8 Aires, +8 Cancer, +8 Leo, +8 Taurus and improve from this. Some Greater agathions give Skill Power(Greater Virgo +5%) or skill Cooldown(Greater Pisces -3%) when enchanted to +5 so keep it in mind.
+5 unique Artifact Book(Atributte attack + Critical modifiers)
Balance Patk, Balance Skill Crit Dmg, Balance Skill Crit rate, Balance Pdef, At least +4
Attack Skill Power, Attack Skill Crit Dmg, Attack Patk, At least +4
Defense Pdef, at least +4
Balance Attribute attack + Balance Attribute Defense + Balance P. Skill Power +11%
Rullers lvl 1 (+8% dmg - 9% dmg)
Enchanted Sigil (+2% Patk)
3x Lv5 Legendary dyes for +15 STR +15 DEX +12 CHA, +1% Patk.+1% P.Skill Power, +1% P.Skill Crit dmg
Epics:
2 x +15-20% P.Skill crit dmg rings(+3++ Dragon ring(Potential lvl3 +5 all stats) // +10 Fallen Angels ring // +10 Angels Ring etc)
+12 Atlas Earring
++8 Angels earring // ++3 Dragon Earring(Guardian lvl3 -5% Dmg)
Frintezza Soul Mind(-13% Cooldown) // Blessed Valakas Mind(-13% Cooldown) // +10 Angels Necklace(-15% Cooldown) // +3 Dragon Necklace(Battle lvl3 +5% dmg)
