Following a series of attacks on a ghost I was expectng my final hit to banish it, but here it was on the global map showing 0% life, still hale, if not hearty.

The report also showed 0%

I have seen extremely low energy levels left previously, but never Zero .

Its annoying enough  having to use one hit for a few %,  but another attack when its already done for,but not banished!.

 I wondered how rare an event it is ,I  am sure there is a technological explanation.
