Depend on resources you have, you can have a nicer MvP build than you have now.
Ow. by the way, I haven't play forsaken-ro for quite a while so my equipment can be quite obsolete.
My Build (20k~22k dmg Demoner for solo - over dmg number for party)
Top Head : Kobold Arhcer Hat - LK (party) and Kobold Archer Hat - Pharaoh (solo)
Mid Head : Ghost Aura - Maya Purple
Low Head : Wing
Armor : Sniper Armor - 2x Gloom
Weapon : Sniper Bow - 3 AK 1 Minor (party) and 3 AK 1 Hunter (solo) and 3 AK 1 SK (solo)
Garment : Sniper Cloak - 2x Chung E
Footgear : Sniper Boots - 2x FBH
Accesories : 2x F.Dex Belt
Stats (STR/AGI/VIT/INT/DEX/LUK) : 25+24 / 30+85 / 130+23 / 4+25 / 300+191 / 150+4 (yes, my sniper is elite char)
Notice that my sniper has high dmg but low hp, but noticably since the MvP buff-ups (that's from ~20m to now) I haven't used my sniper to hunt many MvPs because the lenght it takes to kill one (compared to Champions).
