To prevent the use of ring of protections and the like, the Bardic Chains (Lv1 et Lv2) need to be added to itemexcl.2da with:

COPY_EXISTING ~itemexcl.2da~ ~override~
    APPEND ~itemexcl.2da~ ~X#GARCH  1~
    APPEND ~itemexcl.2da~ ~X#GARCH2  1~

In addition, those items are missing there enchantement level:

COPY_EXISTING ~x#garch.itm~ ~override~
  WRITE_LONG 0x60 ~1~

COPY_EXISTING ~x#garch2.itm~ ~override~
  WRITE_LONG 0x60 ~2~

It is the same for x#iamul Gorion's Amulet witch is an Amulet of Protection and should be added:

COPY_EXISTING ~itemexcl.2da~ ~override~
    APPEND ~itemexcl.2da~ ~X#IAMUL  1~
