General crit multiplier formula; (crit level * (crit multi -1)) +1= final crit multi

Anything between -1% and -100% crit chance would be a crit level of 0 which would out put a crit multi of 1, so the no crit method cited above.

If you can get to -101% crit chance then you've moved to crit level -1 and the formula can start giving weird values. Base crit multis of 1.5x, 2x and 3x will give you values 0.5x, 0x, and -1x.

So healing crits are possible, though unlikely.
