Tame Beast (Companion) Quality reduced reservation doesnt give correct numbers.

Hello,

I have 204 total spirit, and my companion (tame beast) says 43,8% which results in 89,3 spirit. The additional "quality" is reducing the spirit already reserved, which is 10% from those 89,3 spirit... which reduces around 9 spirit, so I only reserve 81 spirit.

The quality is actually low. I thought it would reduce those 43,8% to 33,8% and would help a lot, reducing the spirit reservation to 68,9 spirit instead.

That number seems correct, it doesn't subtract 10% from the base percentage. It "reduces" the base percent by 10%.

43.8% * .10 = a 4.3% reduction in overall reservation.
43.8% - 4.3% = 39.5% reservation cost

Going from 43.8% to 33.8% would be a masssssssive boon for the cost of just 4 gem cutter prisms
