What should I do...? D:

Well, my current knuckle sucks (6 str 88 attack King Sent). I REALLY want a new knuckle, but the only way to get on is to forge a Reverse Knuckle. Well, in JMS, Time Fragments are approximately 2mil each, but I found a store that's selling them for 1.7mil each. A high grade diamond would cost me about 20mil mesos, and then other items needed to upgrade further would cost me about 15 to 20mil more. Then I'd need 7 60% knuckle scrolls (since 30% knuckle is impossible to get in JMS), which are about 2mil each. I have 268mil pure meso and making it would cost me about 120mil mesos. I'm not sure if it's worth it... If I forge it with a High Grade Diamond and a mid-grade power crystal, it'd turn out 3 STR 85 attack clean. If my luck with scrolls fails me, it'll all be in vain and I'll lose that money I spent on forging it.

ALSO! The economy in JMS is extremely unstable at the moment. People are pouring billions and billions of mesos into the Maple 'government' through donator medals, so there's a chance that the prices may deflate. HOWEVER, since there are not a lot of Stat-less and Low-stat players in JMS (kind of opposite of GMS), the prices of those items may actually inflate, due to the high demand.

I'm really on the fence with this one. What's your opinion? Should I do it, or should I try waiting? What would you do in my situation?
