Hi guys, I already made a bug report but wanted to make this common knowledge so ZOS will fix it faster. Right now on the PC EU Ravenwatch no CP campaign, a lot of (mostly DC) stamsorc players are abusing a new set exploit with the Unfathomable Darkness set. When procced by any normal damage instance, like a light attack or direct damage skill, the set will deal static damage that won't change over time, just like the items description indicates. However, when this set gets procced by the stamscorc hurricane skill, its damage will increase a lot over time, just like hurricane does.

To confirm this bug I bought a full set and tried it out in my house on a target dummy. When procced by a light attack, the set dealt around 8.8k damage and this number didn't change over the duration of the proc. However, when procced by hurricane, the first tick already dealt around 11k damage, and continued to increase up to 16k damage in case of the last tick, so almost twice as much damage as it is supposed to do.

Hope this gets fixed soon, the proc meta is already bad for no CP as it is.
