Playing with the devotion skills, found something werid.
Three problem devotion skills name: Scorpion Sting, Eye of Korvaak, Blades of Wrath.
First about other normal devotion skills, their descriptions are like this below (Tsunami as an example) :
A. When player equiped with a main-hand weapon, or equiped with nothing in both main-hand and off-hand, description says
B. When player equiped with only off-hand, description says
In situation A, though description only says 45% main-hand damage, but in actual game test, it dealt “45% main-hand plus 45% off-hand damage”. (Which is werid, feels like skill description bugged.)
In situation B,it dealt only 45% off-hand damage. (Which is normal ,feels correct.)
Then about 3 problem devotion, their descriptions are like (Scorpion Sting as an example) :
C. When player equiped with a main-hand weapon, or equiped with nothing in both main-hand and off-hand, description says
D. When player equiped with only off-hand, description says
In situation C, description says 15% main-hand damage and in actual game test, it dealt “15% main-hand damage”. (Which is correct.)
In situation D, description says 15% off-hand damage but in actual game test, it dealt no damage. Off-hand damage was actully ignored. (Which is wierd, feels like wrong)
So, according to situations above, the 3 problem devotion (Korvaak ,Scorpion, Assassin) skill, if player equiped off-hand weapon/shield, they dealt less damage than other normal devotion skills that has weapon% involved. Because they did not calculate off-hand damage.
By the way, during the tests, I built a mod, just changed the devotion skills a little bit, make them only have X% weapon percent damage left, so that I see the damage dealt more clearly.
Also wonder why this bug would only happen in three specific devotions.
