Soul of Iron is a cosmetic buff available only to characters on Season of Mastery realms that have never died. Defeating Ragnaros, Onyxia, C'Thun, and Nefarian will display a "survivor" text in the tooltip for other players to see.
Dying with the buff will mark the end of the hardcore run for this character and mark them with the debuff. The debuff can be removed from the high elf watchers but the characters can no longer receive the Soul of Iron buff.
- Patch 1.14.1 (2021-11-09): Added.
