All the new skills for Dragon-Blooded Shugengan's. Even their bound spells got an upgrade.
I've been waiting for this lord to get this addition to her skill tree for 4+ years and I'm very happy with this. All the bound spells got a second rank and an additional spell added to them.
Edit: the lower level bound spells now only have 3 charges with 2 ranks instead of 4, but they get 1 use of a stronger spell instead.
