Raise Max Level is an Enhancement that raises the max level of a caught Pokémon. Normally, the max level is 10. The 3DS update v1.3 and Mobile update v1.6 introduced this new item and allowed for certain Pokémon to be able to have their max levels raised, mostly up to 15 (some go up different amounts). The Experience required and Attack Power increase are also updated to include the extra levels.
