It's a field spell that gives you various effects, including:
* Giving your "Endymion" monsters an additional attack.
* Giving your "Endymion" monsters an extra material for Link Summoning.
* Preventing your "Endymion" monsters from being destroyed by battle.
However, it does not have spell counters itself. The only card that has spell counters in the "Endymion" archetype is "Magical Citadel of Endymion (Spell Counter Card)" which is used to power up the "Endymion" monsters.
