Most cost-efficient conjurable units?

Yes, I can guarantee that summon animals is super effective for repairing walls. The hawks drop stones in the wolves'maws, who then send it to the lions, who hold them in place while the spiders use their webs to hold everything in place.

Lol. Bring back memories of Threefort where I spammed call of the winds to keep you out of my cap?

One of the things I like about the lord of the forest is picturing meese manning the walls of TNN's forts.

While I don't like using N gems for anything other than forging and global casting, summon animals gets nice results when cast underwater. And as an added bonus archers can't tear them apart.

As far as best troop summon, I'll go with demons because they're excellent units and don't cost gems.
