Our players loved the idea of this so much that we took a lot of time and work to integrate it into Skill Tree and it works perfectly! You can acheive balance and expand you players options or go all out and make it chaotic! That versatility is what we look for in plugins and I'm super happy to say that NooBlet has got a great handle on that perspective. They've helped us out in providing meaningful contact, and been considerably helpful with some newer additions like permissions and bug fixes. After playing around with the plugin and integrating it into our system, this may have become one of my absolute favorites!
P.S. - We made a video for our players to get HYPED about the new server feature, here it is - SO YOU CAN TOO!

Another cursed (awesome) NooBlet plugin from the dude that brought us The Button and Admin2TeamChat - I think his plugins bring a certain level of really fun creativity to the community, and this one definitely doesn't fall short. I have suggested making the player invisible client-side when acting as an animal (you're already invisible to other players though don't worry) and the developer is actively working on it so that's impressive to see too.

Bonus tip: hilarious for occasional sh*ttery and keeping your players entertained, imagine their reaction when they see a huge polar bear parkouring up the side of their base. 

We really Enjoy Imposter - It is like the druid class  you can fully control the animal and even attack things as an animal. You can use it to be sneaky or spy, such a fun plugin.

Oh wow. This is AWESOME. The reaction that one gets from players. I snuck up on a few inside their bases, turned into a wolf and they are so weirded out. Nooblet has done it again, this is a great plugin. Buy it NOW! The fun one can have with this blood magic is off the charts. Well bloody* done!

*Pun intended.
