It is a description about a skill of an hero in a game and it goes like this:
The spell can cause much damage to enemies with special effects on them.
After I wrote it down, I wondered: would a native English speaker understand its intended meaning? I'm concerned that there may be two ways to understand this sentence:
This spell would cause damage to enemies who already carry special effects on themselves.
This spell would use its special effects to cause damage to enemies.
I want to express the meaning of the first sentence. Is the original wording ambiguous? Is there a simple way to make it unambiguous?
