Help !!! How to use Desecrate gem to call evangelist in the sceptre of god ...

i tried many times but it always is Undying Grappler, plz help me

Port to SOG through waypoint. Use desecrate. Profit! Evangelists often spawn as corpses.

Desecrate is bugged at the moment. If you want you could bump the issue in the bug report section but they are aware.

I hear Desecrate in Invasion is buggy. In Standard has been working fine for me. I did it last night a few times.

Go to the Scepter waypoint.
Cast Desecrate until you see a humanoid.
Move your cursor over it and type "A". It will tell you what it is. (I find this to be a bit fiddly.)
With your cursor on the corpse, cast Desecrate.

If you're using Remote Mine, the corpse closest to you is the one you get, so move accordingly.
