I've seen someone used Stalker's Bjorn's Blade ($30 on Tokenshop) that deal Bowling Bash damage so high they can kill you with 1-2 skill spams.
Things you'll need (based on what I saw before commenting on this thread):
1. Multiple Equipment, eg;
-3 Donate/ Vote Forsaken King Armor
-2 Donate/ Vote Forsaken King Cloak
-2 Donate/ Vote Forsaken King Shield
-2/ 3 Donate/ Legendary Weapons
*Even if the stats are almost similar but even a slight increase can win you in most occasion.
2. Cards, eg;
-Headgears (Maya Purple Card, 3 Kiel D-01 Card)
-Armor (Ghostring Card/ Bathory Card + Tao Gunka Card, RSX 0806 Card + Tao Gunka Card, 2 Tao Gunka Card)
-Garment (2 Skoll Card, 2 Raydric Card, Skoll Card + Raydric Card)
-Shield (Golden Thief Bug Card/ Maya Card, Uskakoring Card, Optional: Alice Card for MVP Hunting)
-Weapon (Randgris Card + 3 Turtle General Card, Incantation Samurai Card + 3 Turtle General Card, Optional: Whitesmith Card + 3 Turtle General Card just to be annoying)
-Foot (2 Fallen Bishop Hibram Card)
3. Stats (this one I'm unsure for Bowling Bash type but Bow/ Double Strifing type maybe like this)
-STR (Enough to carry extra equipment and healing items, eg; Yggdrasil/ Yggdrasil Seed)
-AGI (195 ASPD)
-VIT (I've seen some guide saying at lease 220k with Tao Gunka Card on. But more hp is better for survival)
-INT (None unless you're copying skills that require MATK)
-DEX (As a Bow type I highly recommend maxing this to 300 first then you can put some on AGI til ASPD is 195)
-LUK (None. Only viable for Snipers if they're going for Fast Attack Speed build)
The best way to know what build is right for you is to experiment it yourself. Learn from mistake and adapt from situation. Everyone can be a good player but not without any trial and error. Good luck! P/S: Sorry if this is wrong. I highly recommend you guys correct me on this as I am still new myself.
