What does the wavulavula plant do?
I don’t think they have a use as of right now. Assuming that will change at some point though.
Desmonddark85 is correct, they don’t have a use in the game at the moment.
Will it be for any use soon?
To be honest I am not sure, if I recall correctly PC do not have a use yet for it either. It’ll likely be announced in an update patch notes if a recipe / use is added.
