Blue bricks refer to accumulator charges.
They can be obtained by defeating a holiday monster or from activating a holy powercell, praystation (converting 50% godpower), or sacrificial lamp (converting 50% godpower).
On occasion, generous parishioners may leave a blue brick at a hero's temple.
||Upon reaching your temple, Great One, I encountered a group of parishioners so thick I couldn’t get in, but Gleep soon sent them fleeing in terror. Great! Now what am I supposed to do with this blue brick they left on the altar?
