Ive cleared everywhere.
Got the two resurrects and the increase level.
I can find the tranfser creature to use in Ticke.

Help

Bottom left behind the gold, or otherwise dragged towards a library (blue or red).

Only Found a destroy walls there.
Cant find it in either of those two locations. Dug out everywhere and not in any library.

Can it be destroyed?

Tickle has killed me many times without a transferred creature.

This on KeeperFx . I'm finding this much more challenging than the original which Ive completed many times.

You are not playing the original campaign, but the NG+ campaign, which is a bit harder. One thing it changes is not give you so many transfer specials.

That is the second campaign in the list, the original campaign is of course also bundled with KeeperFX, the top one in the list.
