My current character has 34 Hands. Once I hit 20 I will have 70. 84 may be the theoretical maximum capable of being used for singularity, but it isn't completely improbable. Admittedly it is almost out of my characters reach, but if I had optimized those stats just a little bit better I might have been able to get there.

That aside, the question still stands as to how we are handling all the creatures getting pulled to the center. Do they mass up, get imploded, share squares somehow, or some other solution?
