Power coulds could be.
Increase shortbow and Harpoon damage 5%. Infiltrator’s arrow and Ink shot create a dark field for 3s at your destination. Trick shot,piercing shot and Deluge become 35% combo finishers.
Within the shortbows kit itself a dark field provides life steal which would be additional damage for the weapon set when it procs, and healing for sustainability. As a field it would aid all your allies as well.
The boosted finisher rate on trick shot makes comboing with any field outside of the added Dark field better off which can in turn mean more burning, confusion, blind and the like.
So by specializing in the shortbow, you’ll get greater sustainability and team play.
