New in patch 8.2 is…daylight! For those of us players who care. Buy the toy and/or the consumables.
The toy: use it for 2 hours of daylight at night. It has a 24-hour cooldown. Cost: 1000 timewarped badages.
The consumable: good for 2 hours of daylight at night. The cost: 10 timewarped badages. Used when used.
The name: jar of sunwarmed sand.
The seller: NPC Otela in the Caverns of Time (hint: there is now a portal to CoT in the portal room in Stormwind / Orgrimmar. Then run down to Otela).
The toy did NOT persist through death. But I could use it on more than one character. Good deal!
