Ancient Fragment is a consumable in Job, a mod for The Binding of Isaac.

Can only appear via Sisyphus.

+15% damage to Sisyphus' boulders.
This damage up is exponential, having better effect the more it's stacked up.

-10% to Speed, Tears, Damage or Shot speed, or -1 to Luck.
Stat downs are multiplicative, having less and less effect the more they are applied to the same stat.

+7.5% chance of Ancient Fragment replacing other consumables.

Sisyphus will have its boulder fall chance increased the more ancient fragment is used:
• At 4 fragments, proc chance upgrades to 0.01%
• At 10 fragments, proc chance upgrades to 0.175%
• At 20 fragments, proc chance upgrades to 0.03%
Proc chance increase is reflected through boulders size.
