Tower monsters

Tower monsters refers to monsters that previously appeared in the The Sorceress' Tower (The Stairs), but were phased out with the 2015 tower revamp. While they are technically copiable (and therefore eligible for direct summoning), they become uncopiable (and thus unlocketable) at the start of combat. Current ways to fight them are:

• (genie) wishing
• (HR path only) Rain Man, once you've added to them to your Monster Manuel (or HR-specific-kill-list, for the Manuel-less)

Why fight these things now?

• Factoids
• Completing your flyering in one fell swoop

For the latter purpose, Ice Cube makes an ideal target, as the special item required to defeat it is the trivially-accessible hair spray.
