According to the lore, Garleans can't use magic (and I believe they can't even manipulate aether, though I could be mistaken on that), but Garlean bosses use a variety of attacks that I have trouble interpreting as anything but magic.

For example, Gaius creates "clones" of himself that need to be attacked and defeated, suggesting that they are actual physical manifestations of some sort.

In addition, many Garlean bosses create X-slashes in the air that hover in a static position for a variable amount of seconds before before shooting forward.

Are there lore explanations for these kinds of attacks?
