Spawns a menorah familiar that causes Isaac's tears to be multiplied by the number of lit candles.
The menorah starts with one candle lit, and each time Isaac is hit, another candle is lit, up to a maximum of 7 tears per shot.
Being hit an additional time will release blue flames that damage enemies and set the menorah to 0 for a bit, effectively making him blindfolded. After that time has passed, the candle will reset itself back to 1 lit candle.
Halves tear delay and then multiplies it by the sum of lit candles plus 1. This means that Isaac has the same tear delay at one candle, and 50% more tear delay at 2 candles, and so on.
