Warlock Soulstone Reminder

[bsmorgan]

I mostly solo with my Warlock but I'm terrible about keeping a Soulstone on myself. I'm looking for an addon that will monitor the buff and remind me when it is missing. My search has found lots of old addons but nothing current.

Closest I've come is a WeakAuras reference which I don't understand since I don't use WeakAuras.

Is there anything else I missed?
