The Jade Tan Do is a unique Kris from Diablo II: Lord of Destruction. One of the first unique daggers that can actually do a reasonable amount of damage, the Jade Tan Do's strength lies in its Poison. Not only does it deal a large amount of Poison damage over a relatively short amount of time, it also gives a significant boost to Poison Resist. The Cannot Be Frozen attribute is also a handy bonus.
