Firstly whilst you have an xp boost – get grinding because that extra 100% will make a world of difference to the speed at which your champions level!
Fly through campaign when possible and get to brutal campaign. This is where it is at! The best place you can farm efficiently is brutal 12-3, this gives the best silver and EXP outcome for energy spent. Try to use one campaign farmer plus food, this is because your maxed champion will steal some xp which can’t be used for anything! Don’t waste energy!!
If you can, wait for a double reward like champion training to level your champions to the next star rank because these are easy points. Also on the topic of champion training; you should feed a brew or two into your food champions so they get a few free levels for a bit of brew and some silver. This is free and easy points for big rewards!
Potion Keeps are very useful for xp because it is easier content you can most likely three man it then throw in food champs and gain more xp!
Also Minotaur is similar in this aspect but be careful in mino only use champs you want to get scrolls for.
Don’t do this!
Don’t waste energy!
Don’t burn brews unless there’s a champion training event on!
Don’t push yourself to nightmare campaign – it’s not as worth as brutal!
