I beat the game and now I'm trying to do the sealed doors. there's two bosses I can't keep seem to beat. one is near the dwarfs and the other is in the sky. what are some recommended strategies for these guys. also my characters are level 60. do I need to level them higher? thanks for any help.
I'm also doing the seales doors atm, but there seems to be none that I'm missing. I've done the following:
1. Underwater cave 1 (easy, just use strong attacks and break)
2. Underwater cave 2 (easy, just use strong attacks and break)
3. Underwater cave 3 (easy, just use strong attacks and break)
4. Island ice cave (easy, just use strong attacks and break)
5. Small island covered with 3 tiles of forest (buy ~20 strong weed killers, they do 25k each and boss recovers 60k HP every round, he will die in about 5 rounds)
These 5 bosses gives you the materials for the +5 to all merit point accessory.
6. Cave near the dwarven city (this boss has instant death attacks, buy accessories to protect you from it. He also has a nasty mana drain, so stock up in mana regen items)
7. Sky cave (boss has lots of state altering attacks, place a lot of merit points on resistance)
These 2 bosses gives you 1 accessory each, one that gives 1,5 times gold reward after fights, and one that gives 1,5 times TP after fights. (actually you get the 1,5x gold accessory in the dwarven dungeon itself, the boss only gives you a material for crafting).
Edit: Found the last boss on a small island covered with 3 tiles of forest. This gave me the sapphire and I have now completed all sealed dungeons and crafted the +5 to all merit points accessory.
