I didn't see the usual "New Content" thread for the IotM, so posting this separately. If I missed it I will give the merging job to a minion along with my apologies.
I note that the other two skills -- that have daily limits -- are tracked in daily properties, but this one isn't. Tracking this skill's daily uses would still be useful, however, for determining the amount of deleveling.
Looks like per-combat stuff needs to be reset after casting Macrometeorite. Noticed this when I got a non-tool gremlin (and saw the message), cast it a few more times, got back to maybe the right gremlin (posting this mid-combat so all I know is that it has the same name) but I was told it was the wrong one immediately.
