Treant Leader

The ultimate Plant-type monster and last one of the Leader archetype enemies, this creature is quite dangerous, not only because of its extremely large stats, but also because it's also a much improved version of the Alraune with the same resistances of the Mock Treant. This means it can temporarily disable the Reyvateil's Purging ability, and if it manages to do so, prepare yourself for a much longer and difficult battle, especially if it comes accompanied by other monsters. However, if you manage to take it down, aside of registering a rare monster in your bestiary, you'll also get rewarded with a large sum of experience, so if you ever come across a Treant Leader, make sure to try your best to defeat it.
