The Protect Ring is an add-on that halves the damage from all elements, as well as providing +1 Spirit, +2 Defense, +4 Evasion, +3 Magic Defense, and +6 Magic Evasion. It teaches the abilities Half MP, Long Reach, and Mag Elm Null.

On the one hand, it's super maddening to the OCD completionist; on the other; finding things nobody knew was in the game for over a decade is a testament to how good Sqaure games once were and the feeling of finding it is amazing. Mind you Square's American arm has always been kinda weird about content in its guides.
Colinp42 said: See I find it to be the opposite. I think it's a testament to how games at the time would deliberately put secrets in that one could never be expected to find on your own, thereby driving you to buy the official guide. Just backfired in this case because of the "guide" in question (this was what made me stop buying most guides and go online instead). Not saying anything about the quality of the games overall, but I am 100% convinced that promoting the guide was somewhat of a consideration in game design.
