There are a few maps with tombs in them in the tower defence game Gemcraft Labyrinth, they are often heavily armored and take a while to break open, with a swarm of shadow monsters coming out.
I've mostly avoided opening the tombs until I am strong enough to stop these. What is the reward for opening and defeating one of the tombs? What about maps where there are more than one tomb? Do you get battle amulets, skill points if you defeat one but not the other?

Firstly you get some extra monsters to kill. Also as JonathanJ mentioned you get 10% in your summon multiplier for every tomb you open. Note that all tombs are not the same. There are tombs with higher hit points and armor and the monsters they spawn are tougher to beat (Higher hit points and armor).
Generally it is good to avoid opening the tombs the first time you play a map. You will have the opportunity to come back and replay the map with higher multiplier settings when you reach a higher level.
