Also, in the restore panel, under restoration potion, it should be written as "...100% of of his health and mana" not "1100% of his health and mana". In my opinion, battle banner is a bit imbalance as cd is fast and effect is longer than cd. And it increases really quite a lot of dmg even in lvl 1 besides having extra money n exp.
P/S I would like to print screen all the bugs I encountered but somehow my print screen could not work on gameplay screen.
