So I was playing along, and I ran into a glitch that I posted in bug reports about enemies going into certain areas becoming invisible, but it gave me an idea- what if we had some kind of invisibility field that effected monsters? I had a blast fighting it, so why not make it a gimmick? Chromalisks are disappointingly easy, and the new gremlin recons aren't F2P, so I discount them as enemies. Once you learn where they spawn, its too easy to kill them... and they ALWAYS spawn in the same place on OCH, so its not really a surprise anymore.

Here's how my idea could go-

Option one: Have it effect all enemies. Make it like some kind of large metalic device, and have it in the corners of a large square area (starting in tier 2). Enemies that went into the box formed by the corners would become invisible. It'd spawn randomly in the clockworks, and have its own room.

Option two: Make a new enemy, and have it make other enemies invisible. I'm thinking a new member of the wing family, but that hides a single enemy! Silk-cloak, perhaps? A re-coloration and a new silkwing aura colour would do the trick. Still have the player know when one is about though- don't let it cloak itself. This could be dispersed throughout all kinds of levels.

Option three: Make a new enemy, and have it get hidden by something akin to the statues that trigger invincibility for slags. Essentially, it'd be like an electrical device(though it could potentially be like one of the voodoo statues in design), but then there'd be enemies (probably fiends) that would go about invisible when near it. Nothing else would become invisible for that device. You'd preferably be able to lift up the statue that made them invisible.

So what do you guys think?
