An utterly brutal guy that will make the first 2 scenarios of TFA hell. The cowards out there would recommend not making them angry so these guys are safe to dispatch. Counterpoint; every snake you put in the victory display is one enemy permanently removed from the encounter deck and play areas; you want snakes in the vengeance display so your cluevers can do their job uninterrupted. Instead of making life more difficult for everyone else and forcing them to flee from critters in the jungle and making them heed silly ancient warnings just to make your job as guardian easier, instead bring a set of 2 Handcuffs and bury one deep or something.
These humans with a weird skin disease can hiss from their cuffs all they want about you trampling over their allegedly ancient and powerful culture. To take their warnings seriously is the height of paranoia and folly. If they're so powerful why can they be cuffed and taken to the station just as easily as every other raving lunatic stalking the streets of arkham? It's all hogwash, and surely nothing bad will ever happen to you if you simply ignore it.
