Here’s something strange about the Swarm of Flies:
It’s just one fly.
It most likely says “Swarm” just to explain how it can duplicate. Still, even this doesn’t make sense. Think about it:
If it was actually just a swarm that divides when you hit it, wouldn’t all the stats cut in half, too?
Or, how about this:
Why does the WoT teleport the whole thing? Wouldn’t it just lose a tiny amount of stats, and leave another “swarm” with incredibly low stats?
I’m not even going to bring up why they don’t combine (maybe just the natural ‘family’ prejudice), or why they only split up on physical attacks (distracted by the wand’s light?).
