Completing the Aspects of Interference quest in Destiny 2: Season of the Splicer will reward you with a new Stasis Aspect based on your character class.
Before embarking on this quest, you need to have acquired all other Stasis Aspects.
Since Season of the Splicer launched yesterday, there have been numerous reports of players unable to complete the Aspects of Interference quest due to suspected bugs.
Titans receive the Diamond Lance: Shatter or defeat targets with Stasis abilities to create a Stasis Lance.
