High Templar (StarCraft)

In the real time strategy game StarCraft for the computer, the High Templar is the primary spellcaster of the Protoss. High Templar cannot attack and are rather slow and weak. However, their spells make them powerful support units:

• Hallucination - Creates two copies of a target unit. Enemies cannot distinguish hallucinations from real units directly. However, hallucinations do no damage when they attack, cannot use special abilities, and take double damage. Hallucinations disappear if they are "killed" or once the spell wears out. This can be used for decoys or for intimidation (imagine seeing eighteen huge battlecruisers floating into your base...)
• Psi Storm - possibly the most powerful spell in the game. Psi Storm covers an area with crackling electricity. Any units in the area, both friendly and enemy, take damage for each second that they stay in the field. This is extremelly effective against slow-moving units like the Reaver or Siege Tank or against large groups of small units like Zerglings.
• Archon Meld - only available when two or more High Templar are selected at one time. The Templar merge in pairs to create Archons. This does not consume any mana; however, the merging takes some time during which the Templar are vulnerable. The meld is irreversable, so the high templar and their abilities are irretrievably lost.

Hallucination and Psi Storm must be researched at the Templar Archives. The High Templar can be upgraded for better armor and shields and higher mana capacity.
