NM Spawn Timer (Key Item?)

I believe to help save some time for camping Lottery Spawned NM, or Timed NMs there should a "Timer" when you /heal in the area of where the NM is supposed to be popped. For Example:

When the NM is NOT READY to pop:
(/heal)
"You can sense no threat of [Insert NM Name here] in the vicinity. (Time Remaining: 00:15:00 mins. Earth Time)"

When the NM IS READY to be popped:
"You can sense [Insert NM Name here] is near which sends shivers down your spine."

Also instead of saying the NM's name you can also put "an evil presence". Whichever works I guess.

Edit: Added
This helps when doing multiple quests for your Magian Weapons, so you don't have to sit around for multiple hours wondering when that NM is going to spawn.

I had to waste prescious few stones on questing seals because these NMs are now some of the highest camped mobs in the game. They need to, like the popped NMs make multiple copies, and/or alter these key item NMs to be themselves a forced spawn.
