New hero Storak:
Survive endgame level 3 with 72 or more Demon Commanders, or on Nightmare difficulty, to unlock Storak.
You can only buy Tier 1 and Tier 5 units.
Buying Tier 1 units reduces the cost to unlock Tier 5 units by 10 gold.
Synergy activates at 2 different units instead of 3.
When an allied unit dies Storak is healed for 3% of his max health.
Every time Storak survives you gain 12 gold, but if he dies you lose 12 gold.
You cannot use Bless, Frost Shock or Healing Wave. You can only summon Tier 1 units.
Also Storak has a chance to freeze enemy units for 4 seconds when they hit him. You can upgrade the chance for this to occur, and also the freeze damage.
