Screamer is honestly not the way I'd use Narcus. While yes, it gives you a big chunk of damage in one go, you're also giving up the biggest advantage of the Narcus which is that instead of just letting opponents use their Momentum to boost the effect, you're using your own. So whether that's intended or not, I don't think it's an issue either way.

Narcus is definitely the issue here, the effect gives you such a large amount of free bonus damage over the course of a fight, as long as you can land the hit in the short window. Narcus is especially effective on builds with massive amounts of HP (like the one Fern showed) or on builds that can heal tons of HP.

Narcus is way too free for my liking. I'm iffy on suggesting a hard cap again since when this item was first introduced, it had a cap of your Level which resulted in very few people using it. I think the best way to go about this would be trying Fern's suggestion of it only building 50% of the damage taken so it's more in line with other "retaliation" effects like Crystal Mirror, Brightray Bulwark, etc.
