Worlds of Magic: Planar Conquest (JP)

The fastest way to do this is by using these steps:

1. I recommend a Faction like Grey Elves so you can start with Archers (or any other range unit).
2. Create a custom Sorcerer Lord and put 9 points into the Augmentation Magic Circle.
3. Select the following Tier II spells: Shocking Weapon, Acidic Weapon, Flaming Weapon, and Freezing Weapon.
4. Start the new game.
5. Put all Power into Mana.
6. Start casting each of those spells and place them on a single range capable unit.
7. Once the unit has all 4 spells on it, go attack anything. You can verify that the spells are present by going into Armies Management and viewing that specific unit. Its stats will be shown on the right of the screen.
8. Go into manual battle. Use that unit to damage any enemy.
9. You should see all 4 damage values pop up after the attack. As long as all 4 are higher than 0 the trophy will immediately unlock.
