Challenge Mode/Arkham Origins Deathstroke

Arkhams Origins Deathstroke is the third challenge of Update 2.1, and the first one I'll be covering for his Nightmare difficulty guide.

Arkham Origins Deathstroke
As you can see, this is the most beefed out Deathstroke card so far. Stats and abilities are viewable at this page (Deathstroke/Arkham Origins). Deathstroke has a chance of an UNBLOCKABLE first special, and gets an 8% boost to ALL DAMAGE every time he gets promoted, up to a 56% damage increase. That means his basic and special attacks hit harder. As such, this is a MUST HAVE card for any roster.

Basic Knowledge
Deathstroke's challenge has 189 total battles, 63 per difficulty. Four rounds have 12 battles, and the last round has 15 battles, with the challenge character appearing either as a mini-boss, boss, or souped up boss. It will take 189 Challenge Credits to do so. Every battle can be fought or skipped. If the battle is skipped, it costs Power Credits to do so. This adds a bit of motivation so players don't have to buy their way through. But sometimes, players can't defeat a certain battle, and as such, are forced to skip it. As you progress, battles become tougher, and skip prices become higher as well.

Deathstroke's challenge lasts 17 days from August 7 2014 to August 25 2014. The chart below shows you how much it costs to skip ALL challenges in a round per difficulty. The only one that changes is the final round where you encounter the Challenge character as a boss.
