I have wittnessed a strange occurrence i dont mind but I hate strange things and would imagine this is a bug
I have been on my Death the last few days working on levels and came to need 6 crafting goods from them as the first fight quest in main quest line for ZF.
I saw on the first round one of them had 5 pips worth(2p1n) and it casted a spell loosing 2power pips and nothing happened. Maybe shatter but i doubt for it still used 2 power pips not a power pip and 1 normal pip.
another one casted this unknown spell for 3 pips a power pip and a normal pip. I have seen it at least 4 times once I noticed something seemed wrong with their pips.
Whatever the bugged spell is...it should be addressed unless wizards dont mind the slight advantage lol.
Just to clarify...they are Myth Zebra's in Market.
