Synergies

• Compound FractureIncreases range. Tears turn into bones, which shatter into 1-3 bone shards upon hitting an enemy or obstacle.: Bone tears will bounce normally, and bone shards will only bounce once.
• Cricket's BodyGrants -1 Tear Delay and reduces Range. When tears hit an object or deplete their range, they spawn 4 smaller tears, whose Range and Damage scale with Isaac's./ HaemolacriaTears are now fired in an arc. Upon hitting the floor, an obstacle, or an enemy, they burst into many smaller tears in all directions. Increases tear delay./ The ParasiteIsaac's tears split in two when they hit something.: Tears release split tears every time they bounce.
• Dr. FetusTears are replaced by bombs that benefit from bomb-enhancing effects and slide for a fixed time after being fired.: Bombs bounce, dealing damage to nearby enemies when they bounce.
• The Forgotten: The bone club bounces when thrown.
• IpecacReplaces tears with explosive and poisoning projectiles fired in an arc from the mouth.: The explosive shot bounces, poisoning and dealing high damage to nearby enemies when it bounces.
• 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 tear constantly bounces.
  • The Ludovico Technique + Compound Fracture: Bone shards burst on every bounce.
  • The Ludovico Technique + Jacob's LadderTears fire sparks of electricity in random directions upon hitting an obstacle or enemy.: Electricity bursts on every bounce.
• Monstro's LungIncreases damage and grants a charged shot that fires multiple tears in the same fashion as Monstro.: All tears bounce simultaneously, greatly increasing reach of the burst.
• Mysterious LiquidTears leave a small, short lasting pool of creep on impact or when their range is depleted.: Tears leave a pool of creep with each bounce.
• Pop!Replaces Isaac's tears with eyeballs that can bounce off of each other. The eyeballs are not limited by range, and will instead dissipate when they stop moving or when hitting an enemy or obstacle.: Eyeball tears bounce repeatedly against the floor when they are about to disappear, but can be knocked by other tears to reset their range, meaning tears can be kept in the air forever as long as they are hit when they are bouncing against the floor.

Trivia

• Flat Stone is based on this Steam Workshop item by Maddogs and Joe, originally known as Hydrophobicity.
• It seems as though originally, the lasers produced by the Technology items (Technology, Technology 2, and Tech.5) and Brimstone were meant to synergize as seen in the Concept Art of Flat Stone.
