i've tried searching around but can't seem to find an awnser for what the bonus on the sculpting trait info is forit appears to get higher every time the sculpture is tended too but i don't now what it's for and am exetremely curious anyone have awnsers?

located under the quailty and above the traits sections

looks like Krin forgot to add it to the overview, so here's a link to the spring overview and the winter overview.

But basically:
Sculpts have four tiers of quality, Normal, Good, Great, and Perfect.

Quality rises if you keep the sculpt tended to (Time between sculpts wanting tending: ~1h5m. If you tend it within an hour of it wanting an enrichment, it will rise one Quality stage. If a sculpt isn't tended within that hour, it will drop one stage of Quality instead.

If the Quality is kept up, the sculpt will start getting points towards a Bonus. The rate of Bonus progression will change depending on the Quality (higher quality = faster bonus gain), assuming that it works the same this fest as the others.

Tier 1 Bonus will give the sculpt a stat boost.
Tier 2 will either give a carry (if it's a regular or fabled catalyst. Eg. a sculpt with a lesser pearl will go from being 1v (2tp) to 1v1c (3tp)) or a second stat boost (if majestic)
