Can now heal medium injuries (larger cuts, more serious wounds) on other people as well as himself.
Can now cover his arms in water as protection.
Can now make a somewhat more narrow blast of water that is more powerful and more likely to hurt a bit when it makes contact.
Can create a person-ish sized wave of water. Not very powerful, but it can stagger someone a bit.
OTHER:
Bei still just has the two close friends friends (Atka and Mango, for those with poor memories), but he's met a few more people and would be happy to talk to them more and consider THEM close friends too. Sun is one of these people!
He has met Bao! Personally! And still thinks she is beautiful and wonderful and great and everything is fantastic. Coincidentally, he also has not seen her do anything bad. Fancy that.
He now carries more water with him, since he's been using it more to heal himself and whatnot. He wrapped his new water skins around his arms because, well, it seemed practical, seeing as he always hurts his arms somehow.
Most importantly, Bei now believes that he is high enough level that he can do some good, important work for Crucible of Gaia. He's decided to, along with being a good little Crucible, dedicate a good portion of his time to seeking out people who are being bad. I think we all know what this means.
