10. Wizard Modes
Mr. Sinister: The Megakrakolodonus Rex
Complete both quests and Sauron Multiball to qualify. In this mode you battle the Megakrakolodonus Rex. Single-ball mode with an initial ball saver. Hit blue shots to build up a jackpot and eventually reveal his weak spot at the Lil Deadpool target. While he is in a weakened state, you have 10 seconds to bash Lil’DP as many times as you can to score a 1x, 2x, 3x, etc… jackpot. Assuming he has health left, you return to phase 1 for more blue shots and jackpot building. 15 shots to the target will finish him off and light the Final Shot scoop to finish him off for big points. Also like any other Quest, progress is saved if you drain.
Mr. Sinister: Clone Multiball
Complete Juggernaut/Sauron, Mystique/Sauron, and Sabretooth/Sauron Team-up Battles to qualify. More info needed.
Mr. Sinister: The Final Battle
Complete both Mr. Sinister modes above and Mechsuit Multiball (which you very likely would have by this point) to qualify. Let’s defeat Mr. Sinister (this time it’s personal!).
Phase 1: Timed single ball mode: 45 seconds. Collect the 4 Team-up shots. (what happens if you drain before 45 seconds are up?)
Phase 2: Timed multiball: 70 seconds. Shoot blue shots to collect jackpots until time runs out. Lit Team-Up shots double jackpot value. Hit Final Shot for big points in the last 15 seconds of the multiball. At the end, all balls drain, all modes reset, and a new ball is served to shooter lane. The Special will be lit at the u-turn upon completion of this phase.
