Gate Stone & other item questions

[RicoRico]

thanks for your answers guys! These 'bugs' could have had major consequences for my current MP game had I not known them just in time! :-)

With the pebble stone suit: once you become a troll, does that remove the item (like it 'becomes' your skin), or will you still have the cursed item in your Body slot? And if you are still wearing the item, will you have double regen (+10 from troll and +10 from suit)?
