Cursed Frog is undead?

I soloed a Cursed Frog last night on my bishop while waiting for bosses to spawn and for some reason it took damage from heal. Do you think this was intended?

Well they are not flagged as boss, i can 1hit them with snipe o.O

But they have to make them undead, so i guess it is intended.

Blue numbers appear when it's poisoned.

Mortal Blow works too, makes soloing them both as a BM quick.

Ehh..? Not for me.
Unless it only appears red on my screen and blue for everyone else. Although no one ever said anything about it.

They definitely appeared blue for my Night Walker when I used Poison Sling on it, however the damage was dealt like normal.

I guess this doesn't apply to F/P mages then. I deal 29k damage (regular orange numbers) with Mist.

My bro poisoned it with Poison Bolt or whatever the 2nd job skill is called, we both saw it pump blue numbers.

I've seen it pump blue digits with a little bit of brace on both the frog and cat. Not the best, considering it's not as bad as Bigfoot was at one point. Two shots of either brace or myst, and hope to survive to kite & kill.
