First Impressions: Assassins are awesome!

I recently got to level 23 on my assassin, and received the River Ghost quest where you have to kill the Boss Turtle in the water for a Spirit Orb. I feared my assassin would be too squishy for this and need some help. Which was why I was happily surprised when I didn't need any help. I solo'd that turtle. My tactic? Lots of HP pots, then use Puncture Wound>Deep Sting>swim away and repeat, potting when needed. Considering it has around 13k hp, I consider this to be my most memorable achievement on my assassin so far. You too can solo this boss with enough luck. It can be done!

Edit: Make sure your pots actually HEAL you a bit after using Deep Sting to sleep it before attacking again.
