## Friendship Evolution

A handful of Pokémon evolve not at a set level but when they **level up while their friendship is high** — at least **220** of a possible 255. Golbat becomes Crobat, Pichu becomes Pikachu, Chansey becomes Blissey, and Eevee can become Espeon or Umbreon this way. The Pokémon must actually gain a level for the check to run, so the next level-up after friendship crosses the threshold is what triggers it.

Friendship climbs as a Pokémon stays in your party, levels up, is walked around, and is fed vitamins or healing items; it drops sharply when the Pokémon faints or is dosed with bitter herbal medicine (Energy Powder and the like). Holding the **Soothe Bell** makes every friendship gain larger, and a Pokémon caught in a **Luxury Ball** also warms to you faster.

In the Hoenn games (Ruby, Sapphire, Emerald) Eevee's split depends on the clock — Espeon by day, Umbreon at night. **FireRed and LeafGreen have no day/night clock**, so their friendship evolutions never depend on the time of day.
