No, I'm not saying the skill isn't useful. The problem here is that the skill description seems to contradict itself: if you go invisible, your defense goes up, and you can actually level up the attribute to make the invisibility better at defense. Then, right after it says that, it states that if you take damage, the invisibility ends.
What?
Either the game mechanics of this skill are different than what it says, and someone just doesn't know how to phrase things...or this makes no sense at all. What's the point of having a skill that raises your defense if that defense vanishes the instant you take any kind of damage? I'm aware the invisibility is used for hiding and healing or repositioning, but why even bother with this aspect of it? That means you can just tank one hit from something, which you shouldn't because nothing is attacking you and you shouldn't be trying to get hit in the first place, or have a broken shield either.
Can someone explain this?
Its like a Recon cloak+ a shield.
So yes, they cant see you, but if you do run over spikes, or get hit by an enemy aiming at another knight, you take less damage. Its not meant to be a defensive buff, its just a really nice bonus.
Also, I find the Cloak most useful when Gremlin healers are being a pain in the butt. Cloak, get by all the regular enemies, kill the healer.
