Despite all appearances, the guild facing Elizabeth and the others weren't slacking. Their mages had kept their barriers up for as long as possible. However, the ballistae bolts loaded with runic mines were something unexpected.
Not because no one knew of this trick that the guild Phoenix liked to pull. Everyone had seen the videos of their fort defenses. They loved, absolutely loved, their landmines.
The thing is, they had never shown anyone that those mines could be applied to anything. Sure, dirt hadn't seemed like a good conductor. Everyone watching the streams had thought that they were doing something else. Perhaps a type of special powder or something.
Now, they clearly knew this wasn't the case. Not only that, these "mines" could be applied to anything. The object had to be large enough for the runes to be applied onto.
