Combat Attack Styles interface.
Dominion Staff is currently not giving unlimited to all elemental runes. Also, the Camel Staff is currently not giving Unlimited Air/Fire runes. There might be a few other staffs with the same lack of functionality, haven't really checked.
Shameless plug for HCI:
Will edit as time goes on, or as I find more things to rant about.
