I have a seal with tendonslice 10%/ maiming/ vertigo +10/ +6 enhancement. the tendonslice and maiming worked fine at first but now i do not get any hamstrings or any untyped damage on critical hits. I am not getting any armor bonus from the ring either. the general tab registers the trip dc upon equip, but it is hard to tell whether that is effective when actually using the feat. I went through that quest a lot to get this thing please address if possible.
