20/20 is a passive item.
Effect[edit | edit source]
- Isaac fires two tears at once, one from each eye.
Notes[edit | edit source]
- Unlike other multiple shot items like Mutant SpiderGrants quadruple shot but decreases tears. or The Inner EyeGrants triple shot but decreases tears., 20/20 does not reduce rate of fire, effectively doubling damage per second potential. However, it does not synergize with as many items as the other shot multipliers do.
Synergies[edit | edit source]
- Blood ClotIncreases damage by 1 and range by 5 for tears fired from the left eye. / Chemical PeelTears fired from left eye do increased damage.: Every second row of tears has increased damage.
- BrimstoneTears are replaced by a laser beam that pierces through all enemies and obstacles in its path and deals high damage. Can only be fired after a short charge-up period.: Two brimstone shots are fired, without an increase in charge time.
- DiplopiaDuplicates all pickups and item pedestals in the room.: When doubled, fires 4 tightly packed tears.
- Doctor's RemoteSets a big red target on the ground (similar to the Epic Fetus item) which can be controlled with tear controls. After 6 seconds or by pressing space again, a huge explosive missile hits it, which damages all enemies caught in its blast radius. / Epic FetusIsaac's tears are replaced with guided missiles, like those used by the Doctor's Remote.: Replaces the single missile strike with a barrage of two consecutive missiles.
- The Inner EyeGrants triple shot but decreases tears. / Mutant SpiderGrants quadruple shot but decreases tears.: Adds two tears to each shot, with no extra fire rate decrease.
- Keeper: Fires 5 tears with no fire rate decrease.
- Kidney StoneRandomly while firing tears, Isaac will stop firing and turn red, where he will charge and release a lot of 'tears' in one go. In the burst of tears is a kidney stone which deals a lot of damage.: Increase number of tears in tear barrage; however, only fires one stone.
- The Ludovico TechniqueInstead of firing tears, Isaac controls one floating tear that hover over obstacles. This tear deals constant damage when held in place over an enemy.: The Ludovico tear gains one smaller tear orbiting the main one, each dealing the same amount of damage.
- Monstro's LungIncreases damage and grants a charged shot that fires multiple tears in the same fashion as Monstro.: Adds two tears to the tear barrage, for a total of 16.
- SprinklerUpon use, spawns a sprinkler that rotates and fires tears.: Fires two tears at once that almost completely overlap each other.
- TechnologyReplaces tears with a piercing laser with unlimited range.: Two technology shots are fired simultaneously.
- Tractor BeamIsaac emits a beam from his face. Isaac's tears travel in the path of the beam.: Both tears are fired along the beam. Only one tear can be seen, as they overlap each other.
- The WizTears simultaneously fire out of both eyes diagonally, similar to the effect of the R U A Wizard? pill. Isaac's tears also travel above all obstacles.: Two tears are fired in each direction.
