I've heard of many monks having angelus, granted not level 10 but every little bit of defense helps, and in some cases I've heard of them sacrificing a few buff levels to get it. It's a matter of what you want it for he said he wanted defense so that would mean getting angelus, and really angelus at any level helps, it's only a 5% difference per level so level 10 isn't really a "must". A skill I've never really seen with a monk is cure >.> or signum crucis (don't normally see any use it to be honest) but again it's a matter of preference and what you want... you have to work everything you want into a build that only allows 49 skill points. So you have to play give and take =3
