While the rewards are amazing, for better and worse, underwater combat can pose a challenge, especially for martial characters not prepared for it. Still, encounters are not as challenging as they could be. The bonus fight is also underwhelming. That NPC as a boss, at least for us, was a real push-over.
It gets 4 stars cause the rewards are hard to ignore and it is a change of pace =D
[4 of 5 Stars!]
