There is a thread on this already, but it is locked and the question was not fully answered -> https://forum.bless.gs/index.php?showtopic=55967 For the 2 operations, what are the item requirements to qualify for this service? I bought a non-exc Grand Viper staff to test it out and it seems it is not eligible for that service. Add Damage Decrease Option Add Exc. Damage Rate Option EDIT: Found the information under Bless King Description and work on Exc items only https://forum.bless.gs/index.php?showtopic=54073&hl=service Maybe this information can be on a seperate thread under "Server Features" or this can be noted somewhere directly on the service page.
