1. The Patronus Charm:
* Unlocking the Charm: This is the primary way to defeat Dementors. You must first unlock the Patronus Charm by completing the relevant story missions.
* Casting the Charm: Once unlocked, you can cast the Patronus Charm by pressing the designated button (usually the "X" button on most consoles).
* Using the Patronus: Your Patronus will appear as a silvery, glowing creature (specific to each character) and will chase away the Dementors, allowing you to pass.
2. Using the "Riddikulus" Spell:
* Unlocking the Spell: Similar to the Patronus, you need to complete specific missions to unlock the "Riddikulus" spell.
* Casting the Spell: Once unlocked, press the designated button to cast it.
* Using the Spell: "Riddikulus" will transform the Dementors into silly objects (usually related to the current level), making them harmless.
3. Other Methods:
* Using Lumos: This spell can be used to briefly illuminate the Dementors, allowing you to see where you're going.
* Avoiding Them: In some levels, you can simply dodge the Dementors by moving quickly or using the environment to your advantage.
Important Note: It's crucial to remember that the Patronus Charm is the most effective way to deal with Dementors in Lego Harry Potter Years 5-7. Mastering this charm is essential for progressing through the game and overcoming the challenges presented by these menacing creatures.
