Criticism is the only way you can make a suggestion grow. It's called "constructive criticism". I give that around a lot in this subforum, and try to make suggestions turn into the best thing they can be.

When I have nothing constructive to say, you are left with plain criticism, and I explain it. Editing your post then telling me to silence myself unless I make you feel good is not going to make the suggestion suddenly get any better. I hope you know that.

Now on to your edits...
Apocreans need not to be in this world. From what I recall, they are from another realm entirely, and the fact that they slip over into ours is a rare occurrence. I see no reason for anything to be disguised as an apocrean to attempt to "incite fear into others". Apocreans stay in their realm, we stay in ours, and when those paths cross that's when we combat them.
Angelic wolvers still don't really have a place. Perhaps what you want to have instead is a rare wolver replacement that attacks faster, has more health, and tracks players? Essentially, a harder wolver. If you want it to have a rare drop of an item, you should try to have it be relevant to the rare monster.
Speaking of which, what will this item do? Is it a trinket? An accessory?
