  • Hive Mind Hive MindHive Mind Icon.pngIncreases the size of blue spiders and Blue Flies and doubles the amount of damage they deal. is another shop item to look out for, as it will greatly increase the damage of your Blue Flies. Since you will be generating a lot of flies with Guppy's Hair Ball and Guppy's Head, this will do wonders for your damage output.
  • Tears fired by familiars will spawn blue flies, as will holding any firing key with Rotten Baby Rotten BabyRotten Baby Icon.pngA familiar that spawns blue flies..

  • Bob's Brain Bob's BrainBob's Brain Icon.pngSpawns a familiar that charges forward when shooting tears and explodes upon contact with an enemy, damaging and poisoning them. The familiar respawns after a few seconds. can make this challenge significantly easier, giving a free explosion every so often to fire in a straight line. Any other item that adds an extra orbital or close combat attack like the Yes Mother transformation is a good idea to pick up, since they add damage without modifying your tears.
  • Added in AfterbirthBlack Powder Black PowderBlack Powder Icon.pngIsaac leaves a trail of black powder on the floor. Walking in a circle will spawn a pentagram symbol on the floor, which deals 10 damage per tick to any enemies inside it. is helpful for damaging non-flying enemies and bosses.
