Hello, I have several builds in mind. Maybe you could try one of these.
1)INT max VIT>300 AGI256 Glb&Blb max rest DEX. With 1-2 null autoskill/resist gear and you are untouchable. Or if you want more damage, just equip your best magic gear like HW/M.nin does for armor and add, Gram as weapon, magic/element al and Magic+1% relic. Max I achieve 500k solo with only 1s gear, except sbs. But surviving is hard in solo against high aspd+magic monster like Veleno. You can also switch to auto-atk if you're bored.
2)INT&DEX&VIT Glb/Rlb max Blb max. More HP & M.blade dmg. Null autoskill will also works better with more HP. Equipments are the same above. Imo low survivability against buff/HP wipes boss.
3)Throw+Hide atk build. The STR&INT&CRT max rest DEX build. You can't solo many things with this, only small fries that can be 1-3 shot before you die. Maybe this type could work with STR&INT&VIT>400 DEX235
Boo up◇Ideaus,Honor Cape◇Ideaus,CGB for party play, equip 1-2 negate autoskill or full resist set for solo.
4)Special Throw build. INT&VITmax DEX235 rest AGI. Tysrary,Raiju Jiulong 100,Luke Raider and Special Mirror Throw are the only Spec throw available in the game. Haven't seen people trying this. But I think survivability is high, even without null autoskill/resist.
Maybe try Mirror throw SR◇Sauro2, Strug reup◇Fred, Sage Hat reup◇Dunkelis2 or Honor Cap◇Nigdu or Breezy◇Mr.Ori and CGB.
I never try No.2-4 build. I have seen some ppl using No.2 build in vids, but he/she isn't using null autoskill equip.
