I just learned that if you throw a rock using Mom's bracelet through Multidimensional Baby, it just turns into two tears.
With Mom's Knife in Repentance[]
Mom's Knife now gets doubled going through Multidimensional Baby. There are two adjacent knives that follow the same arc, leaving Isaac and returning, after passing through the Baby. If someone more qualified could edit that in on my behalf, that would be appreciated.
Just discovered if you throw the forgotten's bone club through it, it just vanishes. Should that be on the page?
