Terra is a passive item.
- Isaac's tears become rocks and gain extra knockback.
- Rock tears can destroy obstacles such as rocks and blue/purple fires which can normally only be destroyed by explosions.
- Rock tears have a damage increase with a minor random increase/decrease in the amount increased being different per tear.
- Rock tears allow Isaac to hurt Tuff Twins directly.
- The Rock tears are also able to counter the damage resistance of Blasters.
- Spectral tears make it harder to destroy rocks; such objects are only destroyed at the max range of the tears. Piercing and blue/purple fires are not affected in the same way.
- Damage increase from the tear effect cannot be seen on the hud.
