Hexorbs
Hexorbs are essentially just magical pebbles gifted to you by your friends the elemental spirits, and you'll fire them using your slingshot. You can find these lying around the environments as you play, and you'll want to pick up all of them that you find. They're not only supremely helpful when it comes time to face a boss, they also work wonders for panicking enemies and getting them crowned.
Dryad Hexorb
Dryad's hexorbs will put enemies to sleep and sometimes cause them to panic. These can really help get you out of a jam, and are easy to use often.

Gnome Hexorb
Gnome uses the magnetic power of the earth to magnetize his hexorbs, and these are easily the most coveted hexorbs you'll find. Use them with care, but don't pass up the perfect opportunity when you see it. Enemies and objects that are too close to the orb's blast when you fire it will get sucked toward its center, usually clobbering the heck out of each other in the process. Used in the right circumstances it's all but guaranteed to get you a few crowns with a single shot, or at least bump several guys up into the higher panic levels, and you'll often see lesser enemies beaten out of play before they know what hit them. The damage can be significant, so Gnome tends to work well against bosses. Almost always causes considerable panic in single targets.

Jinn Hexorb
This windy little guy's hexorbs are somewhat the opposite of Gnome's. Instead of sucking everything around them IN, they push everything around them OUT and send it flying. If you've got some enemies nearby a huge pile of rubble, a well placed Jinn orb or two can really scatter the debris and get you some crowns, and they're also very handy if you're getting overwhelmed by tightly packed enemies.

Luna Hexorb
Luna is one of the less generally useful hexorbs, and the moon spirit's power won't cause any panic for you. Instead, it confuses monsters and turns them on each other, which can be very handy if you find that you're outmatched. Pop a cloud of moondust over a group of enemies and you'll quickly find that they'll have softened each other enough for you to waltz in and win. Makes a good getaway tool, too!

Salamander Hexorb
Salamander's spicy little hexorbs are more than just a flash in the pan, as you'll find they're supremely useful right through to the end of the game. They don't cause tons of damage, but enemies will get thoroughly panicked and will catch on fire. Flaming enemies can even run into other enemies and set THEM ablaze, so if used at the right opportunity, Salamander's orbs can create some real chaos.

Shade Hexorb
This dark spirit's hexorbs cause poison status in enemies, draining their HP slowly for around 10 seconds or so. Causes mild panic, making it a useful getaway tool as well as a softening tool.
MAX AMMO: 12
Undine Hexorb
Undine's hexorbs freeze enemies and can transfer that frozen status much the same way Salamander's hexorbs can. Works beautifully for clustered monsters, and frequently works against big single targets. Causes a lot of panic and has a tendency to be handy in boss fights.
