Interesting theory. How many astral window's were present in that battle?

Even if what you say is true. Does it make sense that one or two stone sphere would prevent BF ench?

Consider that I fought pan for a long time and he cast BF ench. all the time. Sometimes there were lot's of stone sphere watching (don't know why, but there they were anyhow).

Don't rush to conclusions that all BF ench. are now impossible due to stone spheres. esp. when there's evidence to the contrary. More likely you hit a corner case, one that needs further investigation.

Now to share my pain: in recent battle my mages absolutely refused to cast my scripted spells and instead blew their gems on stupid stuff. How come?- They had the levels (and beyond), plenty of gems, no fatigue and a serious 1k+ killer army facing them - so definitely a threat.
