BFFS! is a passive item.

Effects

• Increases the size and doubles the damage of familiars that deal damage through tears and contact damage.
  • The size change is only cosmetic: familiars' hitbox for blocking damage or attacking is not affected.
  • Other familiars can be affected in subtle ways.

Notes

• For certain pickup-generating familiars, BFFS! increases the frequency that they drop pickups.
• Familiars summoned by a trinket or by Monster Manual are also affected by this item.
• The blue flies and blue spiders benefit from Hive Mind instead.

Interactions

• Evil Eye: The eyes are not treated as familiars and therefore will not synergize with BFFS!

Synergies

• BBF/ Bob's Brain: Doubles impact damage and increases explosive damage by 25.
• Incubus: Incubus deals double Isaac's damage instead of copying it.
• Juicy Sack: Spawns an extra blue spider.
• Lil Chest: Increases the chance to spawn a pickup or trinket by 25%.
• Orbitals: The damage is doubled as expected, but otherwise the hitbox does not increase for additional protection or reach.
• Spider Mod: Increases the chance for Spider Mod to spawn a battery or blue spider upon clearing a room from 10% to 12.5%.

Trivia

• BFF stands for Best Friends Forever.
• This item is used in challenge #19 (The Family Man).
