How could I miss the potential benefits of this familiar in Hardcore?
Here are some sweet uses for the major yellow ray in HC:
Outfits (knob elite, harem, hippy, pirate, miner, war frat/hippy)
Booze giants
Shaky clowns (clownosity + booze)
Getting elusive items like gremlin juice, scent glands, black picnic basket
Plus, the fam equipment, aside +5lbs, let's you use major ray every 101 turns (probably fixed to 100) instead of 150.
Oh, joy!
Averaging 900 turns per run, it means you get to use it three more times. Worth it (getting the fam equipment)?
