To beat the Elite Four in Pokémon Violet, it is generally recommended that your Pokémon be at least level 60+. Here are the specific levels for each member of the Elite Four:

– Rika: Level 57-58
– Poppy: Level 58-59
– Larry: Level 59-60
– Hassel: Level 60-61

Given these levels, it is advisable to have your Pokémon at a level where they can effectively counter the Elite Four’s Pokémon. Levels 60-64 are often suggested to ensure a smooth victory, especially since you will be facing the Champion, Geeta, after defeating the Elite Four, who uses Pokémon at levels 61-62.

### Detailed Steps to Prepare Your Team

1. Assess Your Current Team:
– Evaluate the strengths and weaknesses of each Pokémon on your team.
– Identify any gaps in your team’s type coverage.

2. Level Up Your Pokémon:

3. Choose Strategic Held Items:

– Consider adding Pokémon with high speed to counter the quick Pokémon used by the Elite Four.

5. Practice and Familiarize:
– Battle a few times to familiarize yourself with the Elite Four’s strategies and your own team’s performance.

6. Healing and Revives:
