Special Operations - All Hallows/Tasks

Hair on Fire
These 25 Tasks need to be completed in order to unlock and recruit Ghost Rider.

General Rules of Thumb

 * Red fights are the most Unstable ISO-8 cost-efficient. Yellow, Blue and Deploy Missions should be avoided if possible.
 * Look ahead and save Gifts (Unstable ISO-8/Pumpkin Bombs, etc.) and Distress Calls in advance.
 * Look ahead and plan your battles. Ex. Waiting to fight the mini-boss (Task 3) until after 3 demons are defeated (Task 2). Sometimes it can cost you an entire run.
 * Mastery Stars can be completed in advance.
 * Spend your Unstable ISO-8 wisely. Unlike previous Ops, almost all of the tasks must be done within this Operations.

Hints on Demon Fights

 * Some demons have the ability to gain health from Burning and Energy attack. Avoid using weapons or Heroes that have that type of damage type. Magik, Gambit, Human Torch, and Phoenix may not be the best choices.
 * BE VERY CAREFUL when fighting the Subcinctus demon. Her Hell Hath no Fury buff results in a massive counterattack. DO NOT hit her directly if you can avoid it (this includes distress calls), but use Recharge, Psychic, Stealthy/Subtle Attacks or Items that do not trigger this buff. (If you have Phoenix or Invisible Woman, defeating this demon becomes fairly easy)
 * Mephisto in mission 3 of the spec ops 'All Hallows' cannot be defeated in the traditional manner. If his health is reduced to 0 during the second wave, he will regain a small amount of health relative to your agent's level. The battle can only end when he uses "Prince of Lies." It is advisable however that your agent along with Ghost Rider (Team-up Hero) and the other hero you use must be kept alive in the second wave. This increases the probability to trigger Mephisto to use his 'Prince of Lies' ability, ultimately ending the battle. Mere one-on-one fight with Mephisto (e.g. Torch vs. Mephisto or Agent vs. Mephisto) may not trigger 'Prince of Lies' ability of Mephisto soon enough, thus prolonging the boss battle.

Hints

 * Task 6: Requires 60 U-ISO and lasts 8 hours.
 * Task 11: Requires 80 U-ISO and lasts 24 hours.
 * Task 16: Requires 120 U-ISO and lasts 48 hours.
