The thunderstrike ability that the star metal greaves are supposed to add does not appear.

anyone know what needs to be modified to get it to work?

i've tinkered a bit, but no luck so far.

i notice it tries to assign the combat ability "thunderstrike"  but there actually is no thunderstrike ability defined in the corespells.xml

instead, there is thunderstrike_spell (which defines the air spell you get for air 3), and the thunderstrike_ability (which looks right for the job)

however, if I change the greaves to give the "thunderstrike_ability"  this too does not work.
