Round table

Sir, I am bringing to your attention that Crypts have a property: they cannot be scouted from the outside, and you should attack them with maximum force.

When you attack a Crypt, you must be prepared to use maximum force; otherwise, don't bother attacking! And Crypts should be taken for any Castle (unless the Crypts are on Necropolis territory, of course). Problems with taking a Castle on difficulty level 111 may arise for Conflux and Swamp, and even then, only if the starting conditions are very unfavorable.
