During this discussion i check other characters cards to see how many differences there are through BI (4th/2nd classic) edition and FFG.
ASSASSIN, look at this topic. Text it's more clear on BI edition.
TROLL: new ability, now with a roll of 6 Troll can regenerate to take one life, instead of movement.
WARRIOR: now he can use 2 weapons at same time in combat. On BI there are some exceptions: Holy Lance, Runesword, Shield. Shield was naturally omitted (it's an armour class object).
THIEF: now he can steal any object (if avaiable on purchase deck) when land on Village, Market or during Market Day Event. Not roll a die...
MINSTREL: now Minstrel can "charm" any number of animals during the game (roll a die, higher than the strength's animal), but during a combat he use only one animal. On BI he may charm only one time for the reminder of the game. Since any animal "charmed" successfully become a follower (and use to sacrifice a.e. on vampire on inner region) to balance this, Minstrel lose his immunity against Hag's Course.
DRUID: new ability, when a Druid land on a "wood" space, recover the full number of spells (of course compatible with his Craft).
PRIEST: Now when Priest automatically destroy a spirit without resorting to combat, not keep the monster like a trophy but gain one spell.
I use italian edition of this game. Regards!
