I have not found this exploit listed anywhere else.
1. After killing a trash mob quickly use your redirect to add combo points to the desired Boss or mob.
2. Equip 2 pieces of tier 6.
3. Use Slice and Dice.
4. Unequip the tier 6 and put your tier 14 back on.
5. Use envenom quickly before Slice and Dice falls off to refresh it.
So long as you do not let Slice and Dice fall off you will receive 5 energy per tick of SnD.
