His base ATK is lower than that of Tyron , which isn ' t high , but definitely not bad . His scaling on 3 rd is very high 770 %. He also ignores dmg reduction effects . That means he ignore the passives of Darion and Dias . Problem is that Darion is going to focus him , and that means doom . If you have a Dias , then you use him for raids , and not for GWDAD . So ye , that is also gone . He does crit 100 % of the time on his 3 rd , and his 2 nd gives him 30 %. With base 15 % thats 45 %. Bad to use as a DD , but good if you give him blade runes 12 %, resulting into 57 %. So ye , if you have super offensive runes like Rage , and almost non existent CR on them , then give them to Karl dark fighter , he can make use of them . Might work for GWO with Galleon Bernard or something . 1 shot something , and pray to crit on 2 nd turn and survive that . Maybe vs something like 2 x support 1 x DD GWD team ? Edit Typo .
