Ancient Osheroth

Ancient Osheroth is a Lords of Cthul monster of the Fiends agenda. Ancient Osheroth was released in Series 3: All Your Base.

Proportions:
 * Height:59 Meters
 * Weight:23,000 Tons

Alpha

 * Since you don't need to worry about screens in morpher form, Despair Tentacle is usually the part you want to keep back at the base for securing and easy healing with a Meat Slave.
 * With red Penetrator and the ability to summon an Elite Corruptor or Cthulabite, you can have each tentacle attack on their own at a -3 def each (and super damage if the target has enough p-Dice to trigger Overload).
 * With reach and occupying a single square, it's impossible for your opponent to completely screen against you (unless they get in a corner and surround themselves with all their units). Look for narrow alleys and clumped units where your tentacles can hide while striking the enemy monster.
 * Don't forget that burrow allows these guys to stand on water. While that does open up some additional options, don't count on using the morpher "snap-back" trick with this monster.
 * Position your tentacles so they are adjacent but the attack leader can use Dismay Tentacle's Hit & Run to then spread the group out. The Osheroth morphers should never be vulnerable to a smash/Beat Back into each other.
 * The Despair Tentacle is very good at disrupting power bases by itself. Consider sending it off on its own to brawl enemy units and Fling them into other units securing buildings or into buildings with low DEF values. Use Telekinesis to move opposing units off of objective spaces or out of adjacency with secured buildings.

Ultra

 * With Telekinesis and Annihilate, Osheroth is an excellent power attacker. Look for opportunities to push screens into hazards to get you an extra p-Dice for such attacks.
 * If facing a ground-bound monster, lock them into a favorable spot with your units. You can then move up Osheroth, sacrifice your unit and make a power attack for 2+ damage and +1 health to you.  That kind of swing usually leads to victory.
 * While a hyper cost of 3 makes Osheroth tempting for a flex game, remember that dropping down will always leave all four of your morphers clumped together into 1 4 square area. With 7 defense, leave Osheroth in her ultra form until later turns where you can move the tentacles into more secure positions.  Don't forget you can sacrifice some units to keep your health topped off.

Mega

 * Mega Osheroth trades the in-your-face style of her alpha/ultra forms for the C'thul traditional turtling style. With Meat Slaves you should be able to heal 2 damage per unit turn.
 * Don't forget that Feeding Frenzy requires an agenda unit to be adjacent to the target. This makes Mollok Brutes the ideal unit to team with Mega Osheroth since they want to be adjacent to their targets anyway (and their massive b-Dice have a good chance at hitting).
