Need some real help with Aryth's Tower. I can't defeat Aryth! I'm like 9 levels higher than he is and I still can't defeat him. Nor can I tell which one is the real one.
I've got the best equipment I have on my battle pets. They are Tiaxche, Delttai, and Crather.

Screenname: Scrollwyrm
How Active are you?: Only just started, but ideally I'll try to visit at least once a day
Mentor Preference (Optional):
How much help do you need? (Scale of 1-10, 10 being that you need Major Guidance): 5-6ish. I've played other pet sims before, so I understand most of the basic ideas, but still have loads of small questions, mainly about breeding & stats.
Other: Thank you in advance. :3

So to make gold you can send your extra pets on missions in the towns barracks.
Use the Barracks to earn gold and get that third slot, it should be your top priority.
You can also sell offspring of your pet but this is not really good unless you have superb animals.
I would back off for a bit and raise your battle pets a bit more then attempt it again.
Pets don't often hand out gold in battle, neither do shrooms. you may get gold from battling named bosses.

Do NOT spend gold healing your pets!!!! Take them off your party and let the heal natural over an hour or two.

Train up to level 60ish and get fabled pets with high stats, they will greatly help you. Make one shadow with both points intelligence and all items oriented to magical power. Make another Air with all points to strength and items with physical power. Make the last a light, they will heal the others, put all points to intelligence with items that help with magical power.

The middle one is the real one :) I killed him and the other two died instantly.

Also stock op on healers and reviving potions

you can PM me with any specific questions you have, Im happy to help!

Thank you SO MUCH for this advice! I'll work on leveling my pets and earning money for the third party slot. :) You are awesome, thank you again!

Your welcome! you can PM me anytime if you have more questions :)

I will take you up on that! :)

It would take forever to get to level 60 at this point. The Forgotten Tomb isn't giving me much experience. My light pet is like 20 levels lower than my main team. Will it still help?

I think which one is real is random? I've killed the middle one and nothing happened.

You can Send pets on missions or purchase and use Experience orbs to level pets quickly, there are also many people willing to train your team up.
