Debes dirigirte a tu emulador en la car`peta conf/battle el archivo client encontrarás esta lineas:
// Maximum allowed 'level' value that can be sent in unit packets.
// Use together with the aura_lv setting to tell when exactly to show the aura.
// NOTE: You also need to adjust the client if you want this to work.
// NOTE: Default is 99. Values above 127 will probably behave incorrectly.
// NOTE: If you don't know what this does, don't change it!!!
max_lv: 99
Modificalas ha tu gusto pero deberás tener el cliente preparado para subir el nivel =D
Saludos!
