So, elemental towel does not seem to be working. +9'd it and +9'd a burning bow, and the damage difference seems to be extremely minor. Nowhere near 45% arrow storm damage boost.
I do 22k without the towel, and with it I do about 24k. That seems that only the EA boost from the natural +9 refine for the 7% ranged damage boost. The SP efficiency for AS seems to work, too.
It for sure is not working with a burning bow.
Please fix.
Also, sprite for Silk Ribbon is not showing.
EDIT: I'll be updating the list below, if you see anything in game or on forums not listed, please post it in this thread. Also, if possible, try to actually test things, as people may erroneously misreport something as a bug. Some stuff is obvious, other stuff may need actual testing in a vaguely controlled manner. If you have a suspicion, post it anyway and perhaps someone else can test it.
=============================================================================
OLD LIST ALREADY FIXED:
Fallen Monk Rosary -- not giving +5 to crit rate
Miracle Blue Rose -- was not casting Aspersio
Kardui Robe -- can be broken via skills in game at +8; demihuman reduction seems to be working just fine (it is currently protecting weapon from being broken, not armor)
Silk Ribbon -- no sprite
Mask of Hero -- no sprite; description missing 10 mdef it gives
Love Piece -- seems to be missing the description and item image (sprite works, though); does not give the 10% fixed cast time reduction when paired with heartwing hairband
King of Spirit Ring -- need confirmation if it should be slotted or not
Imuke Upper Shield -- People are reporting that the "when equipped with horn card" effect is not working Others confirm shield is working properly.
Orlean's Necklace -- reportedly not giving the combo effects of reduced cast time + matk per refine of orlean server.
Mask of Hero -- can be refined (lol)
Toy Syringe -- can be refined (lol)
Cylinder Headband -- not buffing Cart Cannon damage and it is giving a 1 second cast time reduction instead of the 0.1 second cast time reduction (wait this one is intentional? Jesus.)
===========================================================================
Conclusion: Please recheck the items, it will be difficult to test if something like 3% resistance to demihuman is working or not. Would be very good to have someone go through the script and confirm, as many items seem to have issues with sprites, descriptions, or some (possibly all) effects not working.
