Pacification: Ineffective on NPCs?

[Billzey]

The above is incorrect. Pacification will prevent all enemy abilities from firing (excluding spells of course). They can still charge their abilities, but the ability will not actually fire if pacification is still in effect. If pacification does wear off before the ability finishes charging, the ability will still fire.

Basically, it can be used to interrupt any non-spell ability.

They can't start a charge up weapon skill under the effect of pacification, either. For instance, on the first boss in Brayflox Hardmode, if you use shield swipe a second before he starts charging up bomb toss, he will sit there doing nothing for 6 seconds and then charge bomb toss. I assume it's because he is hardwired to use it at a certain time.
