Destiny 2 · Weapon perk
Collective Demolition
Collecting an Elemental pickup or destroying a Tangle grants a stacking period of grenade energy generation.
How it works
The passage gives two triggers: collecting an Elemental pickup or destroying a Tangle. Either grants the weapon a stacking period of grenade energy generation. The enhanced trait improves grenade energy generation. The source does not quantify the energy or duration, or explain the stacking behavior beyond describing the period as stacking.
