. . . . "Red Soul Shard is a Legendary Gem in Diablo III. It can only be socketed into helms, and is obtained by completing the Darkening of Tristram event in January of each year. It drops from Dark Lord (Diablo). This gem periodically stuns the bearer for a moment before releasing an expanding ring of fire, dealing high Fire damage to enemies caught in it. Upgrading increases the damage. At rank 25, it also gives a significant (but short) reduction in resource costs and cooldowns after leveling up. The gem can be used at any Character Level, not just 70."@en . "Red Soul Shard"@en . "Red Soul Shard is a Legendary Gem in Diablo III.
