The best thing is when you can just idle in a fight then when u come back u maybe are finish with much gold and exp or if ur not finish u still have much gold and exp to finish :D
best way to Complete number 5 i would recomend using freeze trap ,athena,phoneixhercules,comet and healing and troops can u chose or look at br34ky on troops and spell and be the green type then (it have most mana at max lvl)
its an very good game but its a bit easy to die and maxing char's and it would been Greate having Shatters and Tomb a bit more easy (thumbs up if want Shatters and tomb to be a bit more easy)
