What is equalized on islands and GvG

For islands such as asura and lushreed, I see that tripods are scaled down to lvl 1 but my engravings apply, so my question would be

For islands which of the following apply :

  • Gear (dmg and hp from gear)
  • Combat stats (from jewelry, I think they are a bit nerfed on some islands pls give % if possible)
  • Engravings (i already know this applies but pls confirm <3)
  • Tripod lvl
  • Gems
  • Cards
  • Feel free to add anything that I might’ve forgotten

Same for GvG (i’ve yet to try it)

  • Gear
  • Combat stats
  • Engravings
  • Tripod lvl
  • Gems
  • Cards
  • Feel free to add anything that I might’ve forgotten

Would apreciate if the answer could have the same format as my question i.e.

  • Gear : no
  • Engravings : yes but x,y,z…
  • etc

Thank you! The pvp is absolutely awesome in this game and even at 3am during weekday the queue for arena is under 10 minute love it! Also feel free to give additional information such as for example : X engraving has a different interaction in pvp etc.
