I have re-done the basic rules mixed with american ones to play with teenagers of my association 2 times a week in my village. Everything had been redone perfectly now, it took me time :
-> Corrections of the monster stats
-> Correction of courage & djiin spells
-> A new armory including the rope, hallebard & starting weapons
-> One new skill for each hero :
-> Barbarian can add one combat dice to attack when life points are equal to 2 or less
-> Elf can reroll dice combat when doing a ranged attack with bow or other weaps
-> Dwarf doesn't need tools to disarm trap, fails to disarm on a black shield
-> Wizard can reroll dices to move when life points are reaching 2 or under.
-> Addition of the chaos spells (revisited)
-> Addition of more artefacts than the 5 ones of the european version.(however I have changed the stupid one time use artefacts and changed effects)
-> Added & modified one spell (djiin) & treasure potion : those card allow to rez a dead hero
-> 14 quests have been done again :
Everything is printed with color laser and plastified now.
I just finished Kellar Keep today and will start on Return of the Witch Lord tomorrow.
I plan to finish like this the basic games and all 6 expansions this summer.
Too much people were asking a more "complicated" HeroQuest so it's almost done now !
I'm still working on advanced rules too...
