Polyphemus

Polyphemus is a passive item.

Effects

 * Greatly increased damage: ${(Damage + 4) \times 2}$
 * Tears down: ${(Delay \times 2.1) + 3}$
 * Tears fired per second * 0.42.
 * If a tear kills an enemy, the tear travels on with any leftover damage.

Synergies

 * : Increases tear delay, and after the first bomb explodes, a second bomb appears where the first one exploded, doing roughly half the damage of the first.
 * /: The tear rate is not lowered further, but the effect on damage becomes a flat +5 bonus instead.
 * : The Forgotten's bone club becomes massive. It deals very high damage but has a very low swing rate.
 * : Allows Isaac to keep his previous fire rate in addition to the massive damage boost.
 * : The rapidly spawning red tears do full damage.

Interactions

 * : The main tear retains the semi-piercing ability and may not burst when hitting a weaker enemy. Split tears do not semi-pierce.
 * : Greatly increases how big the fed tear can grow.
 * : Isaac's tears will block enemy shots and continue, but lose 10 damage. If the tear had less than 10 damage left, it disappears.
 * Piercing tears: Semi-piercing is replaced by proper piercing, with no loss of damage on any enemy contact.

Trivia

 * Much like other eye-altering passive items, Polyphemus has a unique appearance on The Forgotten, appearing as an empty eye socket.
 * Polyphemus, ancient Greek for "The much vaunted", is a Cyclops. He is the son of Poseidon and the sea nymph Thoosa.
 * This item is used in Slow Roll (challenge #15).
