Trap medal and altars

[Holywhippet]

One of the possible medals is awarded after using enough traps on the enemy from what I can see. What traps is it talking about? I've used the trap spell quite a few times but it doesn't increase the count.

Also, my dragon can dig for treasure twice in any given combat. If I level up that ability one more time it says he can search for a single altar as well. Is this like those altars that appear on the battlefield that dish out healing/damage? Is it worth it?

The trap medal improves only when a trap kills a unit (both friendly or enemy) with the exception of summoned creatures.

The altars the dragon can spawn do not include buffing altars, only damaging ones, so they can be more of a pain in the end.

Thanks.

Is there any pattern to the digging with regards to chests/altars? ie. will the first two be chests and the last be an altar which would allow me to choose where it appears? What can I get if I further develop that skill?

[Metathron]

The green spots are chests, the brownish/reddish ones are "altars".

[Holywhippet]

Thanks. That could be worthwhile, although in my experience the enemy troops can and will take out an altar with a single hit. Will the altars always be in their territory?

The possible dig spots are random. Most of the time it is better to use other dragon abilities over digging altars for the purpose of hurting enemies (treasures are a different story, scoring runes and rare spells are great!)
