Having get used to solving his problems with the sword, our Prince, encounters for the 1st time a boss that is invulnerable to sword or magic attacks. So Elika suggests that we have to come to an environmental kill in order to advance.
In a few words all you have to do is to make him follow till the edge of the platform and then make a roll under his feet. Then the Warrior will try to slowly stomp making space for Elika to get in between and hold him back with her magic. At this point u have to fuck the mouse's brains out by clicking to push him away (the clicks have to be quite fast). Then a brief slow motion scene will take place having the Prince kicking the Warrior off the edge. And thats it. The 1st encounter was crowned by victory!
