Haemolacria: The main tear retains the semi-piercing ability and may not burst when hitting a weaker enemy.Shard of Glass: The rapidly spawning red tears do full damage.Rock Bottom: Allows Isaac to keep his previous fire rate in addition to the massive damage boost.It deals very high damage but has a very low swing rate. The Forgotten: The Forgotten's bone club becomes massive.The Inner Eye/ Mutant Spider: The tear rate is not lowered further, but the effect on damage becomes a flat +5 bonus instead.

Fetus: Increases tear delay, and after the first bomb explodes, a second bomb appears where the first one exploded, doing roughly half the damage of the first. Abyss: When Polyphemus is picked up instead of being converted into a locust, it grants all of Abyss's locusts the high damage up without suffering the tears down allowing Isaac to increase his damage rate substantially the more items he uses Abyss on.If a tear kills an enemy and has left over damage, the tear travels on with the remaining damage.Greatly increased damage: ( D a m a g e + 4 ) × 2.Features a strange synergy and a dice room that gives an even stranger synergy!ĩ8G7 307Q - Play as Judas (if you can). A lot of the items are bomb-focused.ĦDHA FGMS - Play as Eden (if you can) should be playable with anyone though. Also be sure to play on hard mode, this run is winnable but still challenging. When sharing seeds make sure to add some details (make sure to hide anything spoiler-y), make sure to include if you played as someone other than Isaac so other people can experience the same run! Seeded runs will also have slight variation based on what you have unlocked. Basically, seeded runs are just for fun not progress.

Seeded runs do not count towards your mom kills if you win, any new items you pick up in a seeded run aren't added to your collection either. To input a seed, go to the character select screen and press tab (on PC, not sure how it works on other platforms) to input the seed. Your seed is shown on the pause screen during any given run and appears as a 8 character code.

Have you had a run with an awesome synergy? Share it here and let some duders play it! New to Rebirth is the ability to share your seed with other people, allowing other players to play nearly identical runs.
