I will create a base class TibiaClient to use singleton pattern like:

tibiapi = TibiaClient(image)
battleList = tibiapi.getBattleList()

It will return BattleList instance:

tibiapi/tibiapi/battleList/battleList.py

Line 14 in f5fd712

class BattleList:

If the image passed in the parameter doesn't find the BattleList, many methods will probably return None. Creating instance every frame is a bad idea.

That's true.
by the way... the base class looks interesting
