look into Touch of the Nictus in your Siphon Lifes and Insights for your dark consumption..those will jack your D immensely at the higher ends..I run an Ice/Dark/Energy..and I love that tank..dang near cried when it hit 50..the only thing you wont be able to really slot on it are prpls, but if you have an emp or debuffer with you..you should easily be able to jack your mish's to 3 and 6 and cook down anything..I use Shadow Maul, Sands, and Siphon Life as my 3 main attacks. couple them with Dark Consumption and EA once they get close and the slows get em..they fall fast. You might see me running around every so often with Oosik...hang out on victory
