Every time I use the Tamsine commune, it shows up as Kertigen's when I use COMMUNE SENSE.

>commune sense
You are not a vessel for the gods at present.
You are eager to better understand your relationship with the Immortals.
Roundtime: 9 sec.

>get oil
You get some holy oil from inside your purple backpack.
>sprinkle oil on amy
You sprinkle yourself with some holy oil.
>commune tamsine
The thick smell of ozone fills your nostrils as the air around you crackles and pops for a moment.
>commune sense
A spark of Kertigen's spirit is within you.

You will not be able to open another divine conduit yet.
The sounds of Kertigen's forge still ring in your ears.

A swamp troll looks at you.

I find COMMUNE HELP to be extremely helpful for remembering what to do, what reagents to use, and when you need to specify an Immortal for communes.
