It is not neccecairy to start a new game to see the other endings. You can go to the menu and load, coming back to the game. You need to start a new game to get those nifty gold hearts next to your save though.
@sputnik2, the trick of the hystory clearing level is to jump in rythem with the platforms. Don't go all macho and try to take multiple platforms at a time. It won't work 9 out of the 10 times.
@activedino, you can get the water using your mob and do a job in the town while you wait. In the meanwhile the guard leaves and you can get your stuff back.
@link2892, after taking an elixer of divine intervention you will get healed a little when you get hit by an otherwise deadly blow. The elixer will work only once but you don't have to get killed in the same dungeon as you drink it in if you want it to work.
@2pur4ulol you can't remove an unit from the map. If you want to change an unit your hero uses, then you need an item like the requisition order in the kingdom store.
Ranged units function the best when placed behind a melee unit. Try putting super soldiers behind war machines. This way, you will have the supersoldier's attack power for longer, without having to pay too much.
