Safe Mode vs Wuss mode

[Romulator]

Safe Mode alters the AI so that they will still seem somewhat hostile, but have their AI changed to not physically attack you. In most cases, they should ignore you, or teleport elsewhere if their AI permits it.

To my knowledge, Wuss Mode simply makes it so the AI cannot kill you. So they may come in contact with you, but there is no "death" sequence. So there is still a bit of fear because their AI still tracks you and tries to come in contact with you, but you cannot be knocked out.
