For Kefka’s Tower in Final Fantasy VI, the recommended character level is generally around 30 to 40. Here’s a detailed breakdown:

1. General Level Overview:
– It is recommended to enter Kefka’s Tower at about level 30. You are overleveled, but the Cave to the Sealed Gate is also relatively easy.

2. Player Experience:
– Players typically reach Kefka’s Tower at levels 35-40. If you’re at level 45, you can easily defeat Kefka with a large party.

3. Enemy Levels:
– The lowest-level enemies in Kefka’s Tower are level 56, but it is recommended to level up until your party is near that level before attempting the tower.

Given these guidelines, aiming for a party level of 30 to 40 should provide a suitable balance between challenge and overleveling. This range allows you to handle the initial encounters and progress through the tower without being overly powerful, which could make the experience less engaging.

1. Level Up Your Party:
– Ensure each character is at least level 30 to 40. This will give you a solid foundation for the challenges ahead.

2. Optimize Character Stats:

4. Explore the Tower Strategically:
– Be prepared for various enemies and bosses, and use strategies like focusing attacks on specific targets to avoid triggering powerful attacks.

5. Save Frequently:
