Materials
You will not be able to cut the tail of the Tobi-Kadachi, but you still can damage it. As this is both its weakest and most exposed part, we advise you to target it.
If you have the luxury, aim for the head as well.
Tobi-Kadachi's Armor
Tobi-Kadachi's armors give you points in two very popular talents. This makes them an acceptable choice for all melee classes.
Tobi-Kadachi's Weapons
The weapons do pretty well at all levels, with affinity, decent damage, lightning damage bonus, and more.
