Maple Warrior 30 skillbook

I am currently unable to find any info on the web about the maple warrior 30 skillbook. Rather old posts on nexon forums dating from around 2008/9 say that at that time it didn't exist or that it came from HT, PB, or premium gold boxes? Could anyone confirm where it comes from? The info isn't on HS or Basil's databases.

Premium gold boxes. HT was glitched and dropped MW 30 for a time, and he either still is or it was fixed already.

Oodles of thanks. Unfortunatley.. I have no idea what premium gold boxes are so I guess a continuation of my question would be to ask what they are and where one would obtain such boxes?

Imagine gachapon but way more hyped up and way more expensive.

Wonderful. I just did some dabbling around on google and it appears as if the m.warrior 30 book is extremely rare and expensive to get. Guess I'll be level my other skills first. Ahh I'm kinda depressed I put my first 5 points into it though :/.

No way. Level 6 MW is the s'hit. Raises my damage so much.

MW30 still drops from HT and it is in the Monster Book data.
