The pirate leader is only lvl 8~10 depending on the character and pets level, Just a few attacks with a basic Lvl1/Lvl2 skill should kill him and his Lackies. Be careful if your lvl 2~4. I recommend being ATLEAST lvl 6. But thats just me. Now, if you wait until you get a pet like Lala/Shiba Inu/Tabby Cat/Persian Kitty, Just try not to let it die. Roca is strongly suggested for her 5 Star Hilt. They only have about maybe 50~70 HP. So they would hopefully die easily. Hope this helps ya~! ;) Ps. Pirate: Lvl 2~3 HP 40~50 Pirate: Lvl 2~3 HP 40~50 Pirate Leader: Lvl 4~5 HP 50~70
