Shadow Shot, d/p3
The strong point of Shadowshot isn’t the damage, but the utility of it. It’s a completely on demand shadowstep with no cooldown, only an initiative cost.
What does any of that have to do with its interaction to a boon? This skill has as much damage as tier 2 heartseeker (below 50%) and should scale accordingly. However, might has no interaction (or very little, in which case…. this isn’t even a balance issue, this is straight stealth nerfs) with this skill.
Unless the multiplier changes with the addition of might, it should scale exactly the same. It has a 1.31 multiplier which is in between a low and mid range heartseeker.
If this is a thing I’d say get it on vid, submit a bug report, and it should get fixed shortly.
Best thing to do would probably be d/p 3 a few times on a dummy, show damage logs. Then have an Ele/Thief or Guardian burst might on you, repeat the same steps above, and then post a bug report if the damage hasn’t changed.
