did you know that if you hold a,s,d,q,w,e and r with everything fullly upgraded then click in the chat box, you get autofire on all of those abilities!
Simple way of beating the end, have everything fully upgraded then defeat the castle after it stops spawning units (might take a while, leave computer on with auto fire on arrows and mana (a&r)) then destroy their castle with hobbits, wait for the end to come anthen SPAM EVERYTHING UNTIL HE DIES!
