i have try, if we can really not kill the final boss in normal mode, yes, we can really not, i explain ^_^
the best magic card with the best combo to kill all ennemi in peace is these 3 magic cards , its a very nice surprise (the bleeding, dont need to lvl up, but the 2 last magic card , lvl up is really important
and if you have 1-2 with this card ( win 2 mana + 3 more card ) , its more perfect, to give him a fair amount of bleeding for the 2 first round and to be ready for the combo
to kill the the werewolf, the big demon ( forgot the name ) and other boss, dead in 3-5 round
in the final boss, archidemon, for the 4-5 round ( i forgot ), after i use my combo, and with this i cant kill him in normal mode, never try in hard, but i think its the reason why in normal mode, he ignore my shield if iam in his side
so it's not a big lie after a new game in normal mode that we have a message that says that we can not kill him
use card --> 40+40+40 = 120 ---> automatically restart again in the same round --> 120+120+120 = 360
this is what i have for fight ( sry my game is in french )
the best artifact is this, for me, if you dont choose a reward ( magic card after each fight ) , it will update a magic card, i am a big fan of this ^_^
and for you, what do you use ?
