Solstice of Heroes have Solstice Engrams available from Eververse!
And speaking of that:
For the duration of Solstice of Heroes, players will earn a bonus Solstice Engram with each Prototype Engram earned through Prestige level-up.
When decrypting Solstice Engrams, players will receive new items until they’ve unlocked all items in the box. Once all items have been acquired, additional Solstice Engrams will award duplicate items. Players may track what items they’ve earned from the Solstice Engram through the engram’s preview.
New item type: armor glows. Players who earn the Solstice of Heroes armor sets may use armor glows obtained from Eververse or the Solstice Engram.
Armor glows illuminate portions of the Solstice of Heroes armor and shine brightest when the element of the armor glow and the Guardian’s subclass align.
Once obtained, armor glows may be used and re-used on any Solstice of Heroes armor piece, regardless of class.
During Solstice of Heroes, players may purchase event-exclusive items from Eververse for Bright Dust.
