Thorn Dancer

The tribals of jungle Proteus are generally peaceful folk. They hunt, gather food and live in harmony with the jungle around them. But that does not mean that they are unable to defend themselves. A large part of their military might is made up of Thorn Dancers. They are agile warriors, famous for using a double ended sword that is covered in poisonous thorns. This info was gathered from the select few that survived an encounter and lived long enought to tell of it.
 

Uri Gudanna mastery

You are proficient with the double ended sword know as a "Uri Gudanna". These weapons are crafted from the living trees of Proteus. It is a two handed finesse weapon that deals 1d6 slashing damage on a hit. If you use this weapon in the attack action then you can use a bonus action to attack with the other end.  

Deadly dance

You have learnt they ways of the Thorn Dancer. In your hands a Uri Gudanna sprouts venomous thorns. Each attack deals an extra 1d6 poison damage. Each time you deal that poison damage to a target they get a counter. If that counter reaches 9  the target becomes paralyzed until the end of it's next turn and loses all counters.
