all you skill get reset wind you leavel the leave by die ing or by use the portal all so if your use in random things you cant use a spectre key to go to the spectre key dimensions with you lost all you new hp and can transform in to bat the right way the own lee way to fix this is to leave you game and rejoin the server/world to get all hp back and have power to transform in to bat again this mend that you cant make a base in the spectre key dimensions
ps. i wann to no in the end game of be a vampire at level 15 well you have 20 more hp then normal
