THIS IS SO MINE:
PvM Assassin Trapper Kickass - Medium Build
The character will be leveled, equipped, skilled and statted within 4 days!

Concept: A very beginner friendly build with an ideal blend of trap casting and melee. Basically, you just cast traps and reatreat from the enemy and should he get too close you can slaughter him easily with the Stormlash and a finalizing Dragon Talon kick. The Holy Freeze Aura of the mercenary will slow the enemy down and help you keep the distance, while the Conviction aura from the merc weapon will do wonders for your Lightning attacks. The Shadow Master is a useful companion that together with the mercenary will keep most of the bad guys occupied. Remember that you can use Cobra Strike combined with Dragon Talon if the enemy slips through the traps and gets up close.
