Losing a fight or going 60 days without fighting in the arena will lose you ranks.
See the Arena Rank page for details.
Winning in the arena obviously depends upon getting exceptional pets and giving them good equipment. A silver eyed witch will do well for her level, especially when equipped with some artifact gear. Bells, meanwhile, are spectacular gladiators when properly equipped. Use Gene Engineering to give Marksman and Eye of Mind to a silver bell, and they will train it rather rapidly in the arena.
The pet arena can also be a good place for the pets themselves to be trained in their martial skills, provided the arena doesn't produce monsters too tough for them to handle, and their potentials aren't terrible - a ranged attacker whittling away at a mithril golem while staying out of melee range, can get off hundreds of attacks before that golem goes down.
Level of opponents scales with the rank, when rank is maxed out, and with current win streak.
You'll receive 100 Yen coin every 5th win and 500 Yen coin every 20th win. In addition, for every 100th win in a row, you'll receive 20000 fame and every pet will be rewarded with 2000*win_streak gold, capped at 600000 gold pieces.
You can now only challenge the pet arena (includes pet duels and team battles but not EX arena battles) a maximum of 3 times every 24 hours.
Your rank during Duel fights no longer determines if you will face <> versions of monsters.
The arena awards have been changed to only count wins and the rewards itself:
- potion of resistance every 3 wins
- scroll of witchcraft every 10 wins
- scroll of growth every 30 wins
- astral light pen every 50 wins
- potion of evolution + potion of descent + treasure map every 100 wins
The pet arena awards have been changed to only count wins and the rewards itself:
- scroll of change material every 3 wins
- scroll of superior material every 10 wins
- craft repair kit every 30 wins
- evolution heart every 50 wins
- random material kit every 100 wins + god heart
Winning 200 and 300 times for either arena will increase the 100 win rewards.
