The Elder Scrolls Online Craglorn patch will include 12-player trials, which are the equivalent of raids but with a bit of a twist: your team will have only a limited number of resurrections available.
Yikes. Here's the silver lining though: additional rewards will be granted to those who defeat the weekly challenge with one of the top times across the megaserver.
Another thing, these raids won't take up hours and hours of your time. They last around the 90 minute mark instead.
