If the killer and the paralyzer are the same monster, truncate
that to "Killed by a foo, while paralyzed". When not the same,
spell out the paralyzer's monster type instead of using generic
"monster". "Killed by a fox, while paralyzed by a ghoul", or
"Killed by a ghoul, while paralyzed by a ghoul" *if* they were
two different ghouls.
