Emberstone

Emberstone puts your guild's most important milestones on screen – automatically, reliably, and without any manual effort. It takes screenshots on its own at meaningful moments and lets the whole guild know when a member levels up.

• Automatic screenshots for your own milestones: level-ups, boss kills in Delves, Mythic+, Arena and Battlegrounds
• Guild-wide level-up notifications in chat and directly on screen
• Fully configurable through the native Blizzard options menu (Game Menu -> AddOns)
• Adjustable delay and automatic quality reduction during lag, so screenshots never hurt performance
• Reliable duplicate protection, so the same milestone is never captured twice
• Account-wide and per-character counters
• Compatible with Retail and WoW Forever

Just install it, adjust it to your liking in the options menu – and never miss an important moment again.
