I just thought of a new idea for an enemy: Evil Knights!
They are pretty much like normal knights; only they are aggressive.
All of their colours would be red.
These guys would probably, (and I'm saying "probably" because I am not sure what monsters have normally,) have worse stats than normal knights.
These guys cannot be healed by gremlins, or silkwings, but they have vials, such as poison vials. The vials vary on what type of place they are. And the knights have 1 health capsule each, (the rank of the capsule/vial depend on what star the level is.)
2 star normal: Cobalt. These guys would have plain cobalt armour, with the blaster, or the calibur, or the blast bomb.
3 star normal: Solid Cobalt. These guys would have solid cobalt armour, and the super blaster, or the tempered calibur, or the super blast bomb.
4 star normal: Mighty Cobalt. These guys would have mighty cobalt armour, and the Master blaster, or the ascended calibur, or the master blast bomb.
5 star normal: Guardians! These guys would have the Azure Guardian armour, and the Valiance, or the Leviathan Blade, or the Nitranome.
I was thinking they would have different types of armour ALSO depending on wh
at type of place it would be. (Say it was a wolver place, then there would be knights with wolver armour, and what ever type of weapon a wolver gives you.) So, if you have any suggestions, please tell it to me!! (I know, these guys would be SO annoying.)
I like your idea, but I would Change some little things:
-make them beeing able to get healed by gremlins+silkwings because these are evil Knights now and as such they are on the same side like gremlin menders and silkwings
-their colour should be either purple (curse-colour, antimatter-colour, fiend-summoning-runes colour, unknown passage's eyes colour) mixed with black (corrupted void enemies) since These are the *evil* colours in spiral Knights
-aside the vials they should be able to use the equal barriers, too
-they should be able to use remeedy pills
note: a similar suggestion has been made in past already. one which I remember was about fighting the void-corrupted Alpha Squad or own imitations of yourselfe.
