Yesterday, the Crucible of Storms raid in WoW opened. It's a small raid with two bosses, with about the same difficulty and item level as the latter half of Battle For Daz'alor. Similar to the Trial of Valour raid from Legion.
First off, there is a quest line leading to this raid. If you have not done so, do a Naga invasion. There's usually one active at all times. A mob will drop the item which starts the quest chain. It's a pretty neat quest, and actually leads into the mechanics used in the raid.
The items in particular seem to have less stats, but an equip effect which is somewhat double-edged. For example, I got a belt which heals you for 70k if you drop below 35%, but deals 60k damage to you over 6 seconds. I gave the belt to one of our tanks to try out.
We decided to try the new raid on Normal, and extend the Jaina lockout from last week. The raid was fairly easy on Normal difficulty. The fights revolve around three artifacts. In the first fight you have work around the different artifact powers, and in the second fight you have to use those same powers to your advantage.
One very interesting mechanic introduced is effects that turn you hostile to the other people in the raid, but do not mind control you. So you're still attacking the boss, but you can't be healed, can't heal others, and you take damage from cleaves.
For Holy Paladins, you have to be careful with Holy Shock. It's very easy to accidentally Shock someone else in the raid for damage if you don't realise that they're hostile.
All in all, it was a fun raid, with some very unique mechanics. The loot is particularly interesting, with lots of weird effects.
