I know this post should really go in the main topic, but I read the post in this topic that told me how to get passed the snowman statue in the Frozen Hinterland. I slide backwards down the ice, then hit the statue's north side.
After that, I slide back up the ice forwards, and walk northwest or northeast. Northeast brings me to a chest that I allready opened, and northwest brings me to a wall.
To the person who couldn't beat Byron, your team really isn't too bad. I'd say get them all to at least 40. Don't keep training Golovath, it's too overpowered for now.
The only really bad one on your team is Rattiera because of it's moves and stats, but the others seem to be good. Wavotamus is a physical attacker, so make sure you stick with physical moves on it. Corpse Cat seems to be good as long as you keep it with mostly attacking moves. Golovath is quick with high special attack, so keep things like Torch, Manatize and Sunshine Song. Ratiera can hit moderately hard with it's standard and poison moves, so if you don't have anything super affective against one of Byron's Manamon you can use Ratiera's Roar and Bite combo to do decent damage. Lantlare is also a flame type, so you might want to drop him or Golovath when you get back to the real world so you don't have 2 flame types. His special attack is high like Golovath, but he also has a second ghost type for more options. Javoltric is fighting-electric, so he can hit standard, shadow, steel, water and air types super affective. It's special defense is also good. Just watch out for magic type attacks, that will kill it. I don't know about what moves he gets, but he seems to be a physical attacker. Here are the types of each of Byron's Manamon.
Molandon: earth (goes down to Wavotamus).
Marlaunt: (ghost, goes down to Lantlare).
Dageetul: (insect and holy, goes down to Golovath or Lantlare).
Paygastorm: (electric and holy, goes down to Lantlare).
Chimerus: (sound and magic, double weakness to ghost but seems to have low defense so anything normal or super affective can take it out)
The starting Manamon that has an advantage against yours (in your case it would probably be Kaborain witch goes down to Javoltric.
