Level 61 to 80

Maple Story Money can help you upgrade quickly. Now I share my experience of level 61 to 80.
Level 61-70: Now its time to get rich in stars. Go at level 60 to 63 and fight red drakes, even though their exp to health ratio is not the best, they drop something almost every sin craves: Steely. At level 64 if you are armed with steely go Zombie hunting for quick exp and money. Get the level 70 stuff now if you did not before. Try to save up for a much needed Scarab in the next few levels.
Level 71-80: Train at Forest of Golems or Zombies. Those two maps have by far the best spawns. The Forest of Golems is very good with Savage Blow and Band of Thieves. Since the Golems are big, they can get hit easily with a jump savage blow. Also there are compressed or concentrated mobs of Golems, so Band of Thieves or Meso Explosion would do wonders here.
As for Zombies, Band of Thieves is not really used much, but the good thing is the platform is big, and once you kill from left to right. You can go back with the same amount of zombies. Forest of Golems' drops are usually crappy, dropping things such as Blood Snowboards, their most common drop, which only sell for about 50k to 100k.
However, they do drop Scroll for Glove for all 60 percents, but it is a rare occurrence. Training in these levels depends on your playing style, although Forest of Golem does seem to give more experience. There are also the Gobies in Deep Sea Gorge II. If you have a lot of money and at least level 1 Meso Explosion, it is great here because it can give about 20 percents to 40 percents per hour.
Meso Guard is highly recommended. If your first explosion does not kill the Goby House, it will use lethal magic attack 2000 damage in Maple story. With level 1 Meso Explosion, it is recommended to drop a few bags of mesos, since deals the most efficient damage when bombing.
