Here’s a bit of info on how this works:

Once Scalecommander Sarkareth has been defeated for the first time on Mythic difficulty, the Cracked Titan Gem item that begins a Legendary weapon questline for Evokers will have a chance to drop from Scalecommander Sarkareth on all difficulties after the weekly reset in the region that he’s been defeated in. The item will be very rare on Raid Finder difficulty (when available) and slightly increases in drop rate with each difficulty.

Quick update on some discussions we’ve seen -

Defeating Scalecommander Sarkareth on the highest difficulty will cover your best chance for getting the Cracked Titan Gem that week. Doing the encounter extra times on lower difficulties won’t increase your chances of getting the item.

This doesn’t apply to regular drops, only the legendary, and you aren’t missing out by doing lower difficulties first.

If a character defeats the encounter on Heroic first, then they will have a low chance to get the item and they are covered for the week. Normal and LFR will not offer chances of receiving the item that week.

If a character defeats the encounter on Normal first, they will have a very low chance to get the item. Then for the rest of that week, Heroic will still offer a very low chance at receiving the item, but LFR will not.

Your chances are the same with these three options in a given week:

• Doing just Heroic
• Doing Normal then Heroic
• Doing LFR, then Normal, then Heroic
