(Red Knight)
But you look like and adventurer
-> But you look like *an* adventurer
(Hunting Fury)
The monsters emerges
-> The *monster* emerges
(Various combat)
The stone eel shoots a ball lightning out of its mouth
The tamed stone eel shoots a ball lightning out of its mouth at $enemy
The elementalist summons a ball lightning and sends it flying at you
(general search/replace) a ball lightning -> a ball of lightning
