Crimson Dragon

To obtain this achievement in the easiest way and less time consuming way possible choose the level "thinning the herd" in the "lava lake" missions this will give you 15000+ experience each time you complete it.I'ts the easiest mission in the game and really easy to obtain 3 "s" ranks on for a total rank of S.Make sure you use a wing man that's max lvl.I'd highly recommend avoiding the wingman secondary power/weapon soleil and it misses the target 90% of the time on this map.The best wingman power is "thousand fists" this will easily eliminate the boss enemies in seconds.If you find the experience is dropping form 15000+ make sure you're using a low level dragon which won't be difficult as long as you've a max lvl wingman.smile
