History of Burning Love

Burning Love is a triumph: as a Sunbreaker, get kills with Incendiary Grenades. The game data has no kill count listed.

How to complete

Play Titan Sunbreaker with the Incendiary Grenade equipped (a Solar grenade that scorches targets) and kill enemies with grenade damage. Unconfirmed: the exact kill count and whether it is tied to a seal or event; I found no page describing it beyond the game text.
