Does Warpath's Apocalyse Whirl node work on Warslash (Giant Splitter node)?

Does Warpath’s Apocalyse Whirl node change Warslash’s base damage to Void?
There is no node description for Warslash node at all. Don’t know its added dmg effectiveness, scaling tags, scaling attributes.
I found information about it on but not sure whether the information is correct. Falling Javelin (from Javelin’s Battle Standard node), its added dmg effectiveness is 200% (750% in its description) on this website and scales with Int. But these are all incorrect.
