What's a butt hose? 😄
Best argument for xoti as a monk or contemplative tank is probably tuolito's palm combined with her free small shield proficiency, since tuolito's palm gets you defensive bonuses, wound generation, can be enchanted to provide even better defenses, and also gets monk fist damage scaling. As a second choice, her lantern is a pretty good tank choice because it helps with defensive buffs, healing, and getting mortification back on kills is pretty nice. Plus you can enchant it for either action speed or spell reflection.
That being said, IME it takes a while for her to get really good at it. Even with a small shield her defenses aren't that great, and you'll need to rely heavily on AR, which is harder for her than other classes (paladins, fighters, even barbarians have better support to get to higher AR). Litany for the Body can help, but you only get one cast until level 13, and all you need is one sickened to take away her +2 AR support.
