My battle pet Loco is tier 11 and can't seem to make a dent in The Hustler besides that little bugger keeps stealing Loco's weapons, can anyone tell me the best way to get around these problems so I can finally cross him of Loco's "to do list" :D

Well first off you may want to mod your weapons with at least 1 Natural Armor Tear Crystal. When the blessing activates it provides an anti-steal. What is your current weapon and scroll sets?

At the moment he has: Rainbow Vortex, Chancellors Shield, Freezing Rod, Phoenix Quill, Reborn Ice Wand of Doom, Malevolent Grenade, Music Note Axe and Twisted Rift Blade, all weapons are with Freezing Baguette Crystals and rift blade has Blessing of Natural Armor Tear Crysta and something else that I can't recall.
Scrolls are: Mist of the Ages, Lava Arma, Poisonous Barrage, Vengeful Tide, Corroding Dew, Gate of Evil and Cobalt Eternal

Well you'll want to add one more Natural Armor crystal to one of your attackers along with a parched baguette crystal because he does like to freeze. You may also want to invest in a Terra Focujin scroll as a good healer scroll is a must.

When battling the Hustler you'll want to try and chain freeze him as much as you can if you can. Try getting your hands on a Gorgun (it's once per battle 100% freezer) helps if you can freeze him off the bat and then just keep damaging him and hope you chain freeze him.

Thanks heaps I really appreciate the help
