i didn't find any info how much exacly should skills change during enchantment but some skills when enchanted to + time give very low ammount of time. for example: - tank skill knight frenzy enchanted +10 time last 1 minute 20 seconds, skill deffinition says it should be 2 minutes. - tyrr skill berserker rage and boost enchanted +10 time last 1 minute and 6 seconds oo - tank skill final ultimate defence +10 time lasts 40 seconds, skill deffinition says it should be 1 minute in past chronicles and even in this one all skills enchanted on max value at time changed duration to make it twice longer as it was ( iss enchanter sonatas, tyrr warrior second wind/ totems ) but those skills i mentioned above look strange so i would like to know is it a bug or it should look like that. if this isn't a bug it's useless to enchant + time on those skills, paying a lot of adena for 6 more seconds on berserker rage or boost when enchanted to +10 is waste of sgc and money.
it should be 1 second per enchant. 1 minute ud, 2 min knight frenzy would be unbalancing olympiad pretty hard (dont forget you can crit those skills and get ud then for 2 mins and knight frenzy for 4 mins.)
