Sun Shard is a trinket in Fiend Folio, a mod for The Binding of Isaac.

Spawns a familiar that deals 50% of Isaac's damage on contact per tick, 4.29 times per second, and blocks enemy projectiles.

The familiar has a different appearance each room, and has different effects upon blocking a shot, based on its appearance.

Venus: spawns a brain familiar with 20 HP that leaves damaging red creep on the ground that rapidly deals 2 damage to enemies. The brain will go after enemies and deal 8.66 contact damage. Only 1 brain can be active at once.

Earth: shoots a burst of yellow projectiles at the nearest enemy, each dealing 1/3rd of Isaac's damage.

Neptune: causes the familiar to move in a circle for 4 seconds whilst leaving damaging red creep on the ground that deals 1/3rd of Isaac's damage, and occasionally leaving projectiles in the air that deal 3.5 damage but quickly fall to the ground.
