Metal Parade Guide for noobies.

1. Energy required to enter the parade is 15. 
2. Maximum number of monsters you can acquire per run is always 5.
3. In addition to the 2nd point above, you can only acquire a minimum and a maximum of 1 metal ghost / king / god per battle.
4. Metal God = 20hp, Metal King = 15hp, Metal Ghost = 10hp.
5. However strong your hero's attack is, you will always deal only 1 damage per hit to a Metal ghost / king / god.
6. For efficiency in farming, it would be best to bring a team composed of Heidt, Stya, Douglas or any other hero that hits normally for a minimum of 10 attacks / hits per turn.
7. Metal Gods doesn't necessarily need to be the boss of the final stage / battle. It can appear as early as the 1st battle.
8. To acquire Metal Kings easily (99% success): when you encounter a metal king plus 2-4 metal ghosts, make sure to first defeat all but 1 metal ghost, then proceed to defeat the metal king. You will have a higher chance of acquiring that one metal king. If you encounter two metal kings in one battle, then just kill any one of them first, then proceed with the other. Point No. 3 will then apply.
9. If you run out of gems or you don't want to use any gems further to restore your energy, leave your game as is inside the metal parade entrance screen and wait until your energy becomes 15. You will still be able to Enter the Dungeon even if the time had already expired and the dungeon is closed normally.
