A great tactic has been found. If you use cracking bolt and rolling flame from a long distance, the enemy will not notice the party, which in turn means endless spells. This method allows you to destroy almost any encounter or lure enemies one by one increasing or decreasing the distance. Also, since the spells are power level 2-3, This strategy can be effectively used by any wiz-multiclasses, making the strategy a great way to complete solo PoTD. If you a smart wizard, you should practice sniping.
Also, if an enemy encounter contains healers trying to kill someone is pretty useless unless you can kill mob with one blow, but in this case, such exploits are simply not needed. Still great for luring.
