These 2 pieces of armor were succesfully enhanced (without forged tool of artifacts) with heartwood but do not show any extra properties. The gauntlets before enhancing were: 9/7/17/3/13 (17 cold was imbued), Hit Point Increase 5, Stamina Increase 8, Lower Mana Cost 8%, Hit Chance Increase 5%, Strength Requirement 70, Durability 255/255 The arms before enhancing were: 6/7/17/6/12 (17 cold was imbued), Hit Point Increase 5, Stamina Increase 8, Lower Mana Cost 8%, Hit Chance Increase 5%, Strength Requirement 80, Durability 255/255 So basically the armor pieces had 5 mods before enhancing. 1 reforged: 5 HCI. 4 were imbued: resist, HPI, SI, LMC. Possible properties added with heartwood: Luck 40, Durability 50%, Lower Requirements 20%, Damage Increase 10%, Lower Weight 50%, Hit Chance Increase 5%, Mage Armor (removed in one of the publishes) Was durability the property added with the heartwood enhance? There is no way to tell because powder of fortifying was already applied to the armor to a max of 255/255. But if durability was added, shouldn't we see a property like +50% durability? Or is this a bug?
