Sorry all for sounding a we bit ignorant, but here is the question. during the last boss war I reached level 2400 at which point xp points to advance doubled, i.e. instead of 24010 xp needed it was 48020, is this just one of more surprises to come? thanks ad
Eventually when you hit certain break points in the game the amount of experience will double. Usually every 2500 levels or somewhere close to that is when it will double again.
Level 2500 and 3000 see further increases in XP needed to level (XP = levelx25 for 2500 - 2999) and XP = Levelx30 for 3000+ I don't think there are further increases after these.
