ToME 2.3.5 - How to use The Cunning Plan of Zog

[Wraith]

I found artifact The Cunning Plan of Zog and I do not know how to activate it.

Commands m, a, A, u, U, z or w do not interact with this item.

You should just be able to 'A' activate it. The 'A' command defaults to showing your equipment, so you'll need to switch to your inventory, which IIRC is done with the '/' command.

Note that corruptions can be character-ruining, so activate this one with caution. But hey, at least it doesn't activate for death!
