- In-game description

Red Ring is a rare barrier that is considered to be the best barrier in the game. It is equippable by all classes, provides passive HP and TP regeneration and gives a +20 boost to all stats along with a decent set of resists.

It is notorious for being the most difficult barrier to obtain, only dropping from Dark Falz at a low drop rate.
