A beacon gives heals or temporary buffs to any monsters in its proximity. There may also be beacons on some levels. Spending a gem on a shrine causes more damage than spending it on a gem bomb. By sacrificing a gem, you may activate a shrine and get the effect for that particular shrine type. Some levels have shrines of various types on them which can be activated.
