directly? I haven't test it in game to check the bow's support skill is using which one or not (they are different in both damage penality and mana multiplier ) Neokowloon (talk) 13:36, 9 February 2020 (UTC)
- Answer to myself. Tested with tooltip damage and mana cost. It seem the bow no longer use it own Greater Volley skill and numeric value, and instead using the same numeric value from lv 20 gem. Also pypoe return no result for extracting "UniqueSupportGreaterVolley". Neokowloon (talk) 07:01, 13 March 2020 (UTC)
- And it seem reflected in this datamined change Special:Diff/584770. Neokowloon (talk) 09:34, 22 March 2020 (UTC)
