For the sake of my sanity, the Vinemaiden is not going to have its full taming functionality on 2.0.0βs release.
Specifically, the ability to set it to a burrowing mode where she will gulp up any hostile mobs that enter her radius and then return to her original spot after will not be in the update (THIS WILL STILL WORK FOR HER UNTAMED FORM THOUGH). She will still be able to follow/stay/wander though so she can still behave like a normal Ally (pet), so donβt worry.
For my own sanity, that feature will be pushed to 2.X.0 (a sub-update). Iβll be releasing a planned roadmap for updates when 2.0.0 drops, so Iβll figure out when I want to approach that then.
