Effects[edit | edit source]

  • Visually increases the size of all familiars by 25%, and improves the effectiveness of most of them.
    • Doubles the damage of Familiars that deal damage through tears and contact damage.
      • Only affects familiars that deal a set amount of damage. Has no effect on most familiars that scale with Isaac's damage.
      • Has no effect on Creep generated by familiars.
    • For pickup-generating familiars, increases the frequency that they drop pickups.
      • Familiars that require clearing a certain number of rooms will require one less room.
      • Familiars that have a random chance to drop items have a higher chance.
      • Familiars that pick up consumables require less, except Dark Bum Dark Bum which is unaffected.
    • Some familiars have unique synergies.

Notes[edit | edit source]

  • The size change is only cosmetic: familiars' hitbox for blocking damage or attacking is not affected.
  • Familiars summoned by a trinket or by Monster Manual Monster Manual are also affected by BFFS!.
  • The Blue Flies and Blue Spiders benefit from Hive Mind Hive Mind instead.
  • Does not increase the frequency or effectiveness of Status Effects applied by familiars.
