[NDS] Dragon Quest Monsters: Joker Quick Walkthrough (Part 17 - Vs. Dr Snapped) 

This is the 17th part of my quick walkthrough for DQM:J, covering the final boss battle against Dr. Snapped.
Before starting the final battle, you can go back to the sewers to grab another free Rank-A monster.
Dr. Snapped is rather difficult; he has a lot of HP, and he is not alone. You will have to defeat two of his minions first, each of which can hit quite hard. Then, he will fight you alongside another two minions: a Tortured Soul, and a Demon-at-Arms, who has Double Trouble.
Just to make things even harder, Dr. Snapped himself also has Double Trouble, and a hit-all spell that does heavy damage!
If you have any Double Trouble monster, it will make things a lot easier, but don't be afraid to issue direct orders when you need to. Also, make sure you carry at least one Yggdrasil Leaf in your hand (not bag!) to revive any KO'd monster.
In this walkthrough I will briefly guide you through the main islands and dungeons of the game, and show you where to go and what to do, etc. However, I will not tell you what monsters to catch, what skills to learn, and etc. - those are for you to figure out on your own, as customization is a big part of the fun.
Hint: This isn't Pokémon, and the species of the monsters are not as important as the skills and traits they possess, since any monster can learn any skill in this game.
Also, I will not probe every nook and cranny of the map to find rare monsters or secret items (look on GameFAQs for those), but I will show you the locations of all the important items, which are only a handful in the game.
Lastly, this game is really not that hard, so if you find a stage or boss too tough, then it's time to upgrade your monsters, and especially their skills. Remember, focus on skills, not species or stats! (If you just want to enjoy the story, then those super-complicated, chain-synthesized uber-monsters are just not worth your time!)

Thanks for watching!
Footnote:
1. I will try my best to avoid spoilers, so I usually skip all story-related cut-scenes.
2. Due to time constraint, I will try to avoid unnecessary battles, or edit them out after. I will also do all my grinding, catching, and syntheses off-screen.
3. My parties in the game are purposely over-leveled, because I want to get through the stages as quickly as possible, without grinding on the way (which you'll probably do).
*4. It's hard to do video walkthroughs for this kind of games, so comments and suggestions are welcome. But, if you don't like it, please kindly go watch something else, and don't flame.
