Hello,
I found an easy way to kill the Alpin Dragon in Hard Mode.
I Focused on destroyed all small enemies
After a hard fight, 5 of my characters were killed. It stayed just the Alpine dragon with 3/5 of his lives and my main character, a solid warrior with the characteristics of Eldér.
My warrior had a Level 14 and was equipped with the Blade of endless paths affined at Durgan Forge + Boots of speed (+3 move speed).I’ve just turned around the dragon, I’ve struck him in his back … I've continued to turn around. At no time, he could touch me. After about 10min, the dragon was killed.
No magic, no special technics, just patience….
Good luck for using my manner of doing J
