You can pull inanimate objects towards you using a PULL command. This attribute exists primarily to fill a gap in PULL attacks, which allow builtin characters to use them on props but dont allow the same for customs.
Important: Due to FFX Control Centre having a limit on the number of customizable attributes, Webslinger has to be customized manually by opening ffxcustom2.py:
### Web-Slinger FFX_WEBSLINGER_CUSTOM=[ ["default","ffx_web_pull"], ["types","dDummy Power"], ]
