Disney Infinity 3.0 go from level 0 to 20 in 7 minutes

So I've found that raising the combat difficulty to Extreme does indeed increase the amount of sparks you get. I also managed to make a new spark chamber that works, seems I can only get it to work with the Rhino guard enemies. Also, at least for me on PS4, using the spark chamber at Extreme difficulty causes the game to crash after 5-10 minutes, and boot me straight back to the PlayStation Dynamic Menu.

As for the disc to use, the Donald Duck Costume gives you a chance at bonus orange sparks, which is needed for leveling. Also, I use the Alien Symbiote disc for extra pick up radius, like Merlin's disc, in case you can't find one.

I tried my 2.0 Spark Generator today and it seemed to be working well. One thing I noticed was that it also levels up your sidekicks to max friendship really fast.

I saw the post yesterday about duplicate discs giving a higher percentage. It didn't work for me. I didn't realize you needed 5 for it to kick in. I may have one or two more that I have that many of. Right now, I'm sitting on 249.5%.

Made a Spark genrator (All thanks to Jason Haines' insanely helpful tutorial) and seems to work great.
However, I have registered all my 1.0, 2.0, and 3.0 characters (The only ones I am missing are a few Crystals, Obi-Wan, Fear, Black Spidey, and both Tron) Yet I am nowhere near where Sheriff is in his spark bonus. I doubt around 8 characters make a difference, especially considering the bulk of those 8 are 1.0 characters and only give me 1% bonus.
So Sheriff, how exactly did you get so much from your characters?

Every time I leave the Wii u on the game freezes at a random point while in the spark plug level. I noticed it froze twice when I had 30-40k Sparks.

What really made me mad was once I turned the console on I lost all the Sparks but I still had the experience (so I was level 20)

Yea spark generators can cause consoles to freeze. You need to save regularly so you don't lose your sparks

Great stuff. Thank you for this thread. Used Jason's video to make this. Up to about 242% using Merlins Summon and Lucky Dime. Taking about 6-7 minutes. Only running 3 enemy generators also. Don't want to freeze the system.

@Stitch

You said the bulk of your 8 were 1.0, but you listed five 3.0 figures that you don't have (Obi-Wan, Fear, Sam, Quorra, and Black Spidey, who is counted as a 3.0). Those five right there, would give you an additional 25% bonus. I have every available figure except all of the Inside Out, Luke, Leia, and Boba Fett. I put on as many duplicate disks that I have (maybe 50), and my spark bonus is 250.5%.
