I've dealt with both teams. I do think Mursilla's team is a lot tougher. However, Rena is the better one for people on a first play through of the game.

I actually think Rina's team is tougher than Mursilla's, largely because Mursilla's team is so slow.

Volanteril is a pretty big threat if it gets going, as it hits like a truck, but it's also weak to a lot. Kamadeir is tanky enough, but it's slow. Brain Dodderator is just dead to one of its many weaknesses. Rescumo is bad, I have no other words; pure ice type that's mid-fast and super-defensive with bad HP and meh to bad attacking stats...no thanks, not on an ice type. Tarboo has decent enough stats, but bad moves, meaning it's just not a big enough threat. Again, Maustadon has beautiful attack, serviceable defenses and good bulk, but it really doesn't resist much except, like, magic and poison and plant. Everything else it's either neutral or weak to.

Rina, on the other hand, has fairly fast mons. Submenno has decent coverage, and Araknite does too if it survives. Bulderdash may have meh defenses but it has a nice ability and it usually gets one or two attacks off. Blade Dodderator is, again, just bad, and so is Mondevol unfortunately, but Sirenea is fast, fairly bulky and gets STAB on two useful types.

If teachable moves were a thing, here are the reimagined teams I would give each stadium master:

Mursilla
Volanteril with Secondary Scale Uniform: Earthquake, Assault Gem, Draco Breaker, Call to Arms, Fury Power
Kamadeir with Angel Pendant: Attack Prayer, Staff Slash, Clobber, Hibernate, Defense Prayer
Guerrerrol with Root Point: Power Punch, Gammadrain, Hone Blade, Slash, Toxic Tail
Maustadon with Chrono Core: Earthquake, Mindless Charge, Compact, Crystal Slash, Stone Pyramid
Tarboo with Power Bracelet: Earthquake, Aquatic Blitz, Call to Arms, Decibel Rush, Scourge Tail
Dussocket with Requiem Hourglass: Chomp, Superspark, Aerial Caper, Aura Master, Iron Maiden

Rina's Team
Submenno with Power Bracelet: Aquatic Blitz, Crystal Slash, Powerfang, Slash, Hone Blade
Bulderdash with Ambush Guard: Rev Up, Protect, Stone Spin, Swift Slam, Earthquake
Sirenea with Tank Immunity Bracelet: Shadow Sphere, Flood, Hone Mind, Psychedelic Spell, Psychotrick
Garganchan with Resistor Advance: Earthquake, Power Kick, Roar, Blaze Rampage, Stone Pyramid
Fowlusion with Chrono Core: Wing Slash, Aerial Caper, Berserk Branch, Pest Pincer, Staff Slash
Mightauras with Requiem Hourglass: Earthquake, Iron Maiden, Hone Blade, Sludge Hammer, Thunder Hammer

Still not perfectly balanced, by any means, but to me at least, that looks a whole lot better than what we've got.

It's just easier to deal with slower mons. As I pointed out, four out of six manamon on Mursilla's team are weak to steel, and most mons on that team, bar Rescumo, are slow as well. If you have a mediocre-speed steel type, you will destroy her; if you don't, or if you get caught up short by letting something get going, then yeah.
I'm not intending to be pushy and I do support your right to a different opinion, but I've beaten the game a total of nine times, each time with a slightly different team composition. I hope for Rina every time now even if I don't get her, and I've gotten Mursilla three or four out of those nine times I believe. her team is just easier to exploit or set up on. Rina's team just doesn't have quite the same glaring weakness, is all, so unfortunately, data doesn't lie. Statistically speaking, a player is more likely to have a challenge from Rina over Mursilla.
But as I said, neither of their teams is really all that good.

There is a bug with the florgeril line. it have 2 different abilities, but both of them show up as Cloud cover. the other one increase it's accuracy of electric type moves in rainy weater.

PD. It seems Clear vision and eagle eye does the same thing, both of them increases accuracy.
The same thing happens with determination and angry disposition. Anyone knows if there is any difference?
I need to breed eagalas to know if it have 2 abilities, the ones that I have for now have Steadfast but if it have not eagle eye it would be... weird

My guess is that grave heart is the same as burning/sparking/drowned heart. Someone's going to have to confirm this though.

Re, music: No, it isn't free. However, there's a pretty good chance it's not a purchasable asset either. Not all the music in Manamon 2 was custom-made (I believe the Brightanburg theme may actually be used in Last Week Tonight) but I have a good feeling the Barren Byron fight music was probably custom made. There aren't many off the shelf royalty free tracks with lyrics that actually make a lot of sense. Lol!
I assume if Aaron is allowed to give out track attributes, you would be able to find out the artist that made the song.

Its not custom, i found it a weak ago

hay everyone! I'm doing a manamon2 live stream, and I hope that you all could join me. The name of my YouTube channel is called Labron Minnis. And the stream starts at 10:00. If you all decide to join me, I'll be delighted to have you guys on the stream. So come on please join the stream, and let's have some fun!

Has anyone tried the new unknown gift?

Hi,
Does anyone have any hints on how to find the last two black matter husks?
I know one is in the lower catacombs and one is can be obtained somewhere in the swamp. I just want to know where exactly they are, I already spent a huge amount of time wandering around the lower catacombs and around the swamp.
Any help would be appreciated.

Hi,
@Jack: Thanks for the pointer. I have another Problem. When trying to collect the black matter goo in the tunnel near shadow Canyon I can dive, but I don't know how to continue from there.
