I was watching video about woodworking and engraving the other day and i thought to myself, hey it would be cool if we have things like this in haven, not only it would be super fitting thematically- people of yore would decorate everything they could with engravings and painted patterns- it could be an interesting mechanic too.
I know there are quite some people who play H&H solely for the game of chance with gilding/gem cutting with a hope of creating truly LEGENDARY artifact. This suggestion is about the same thing: spending months of work and tons of resources to flex on your neighbours with your gucci stone axe.
So my idea goes like this: basically engravings would be sort of gildings for the tools but with a twist: instead of providing stat/skill bonus like every gilding does they would give minor bonus corresponding to tool's purpose. Like extra speed when cutting trees for an axe, a small chance to get extra crop for a scythe, or reduced stamina drain for a shovel. I do not suggest it to be another Q boosting/spiraling mechanic! There would be couple of ornaments to choose from like knots, waves, vines, skulls and such which provides specific bonus when applied to specific tool, so trial and error mechanic cooking style yay.
And then there coming the casino part: each ornament have a chance to be successfully applied based on chisel q, tool q and heartlig's will*dex*psy*smithing/carpentry, failed engraving would result in "botched engraving" that gives penalties instead of bonuses. Each consecutive engraving on the same tool have smaller and smaller chance to be successfully applied to the point being abysmally low. And now the most exiting part of it: some engravings may combine into bigger one for example sea+trees=knarr, knarr+skulls=Naglfar with bigger and more sophisticated bonuses a little extra motivation for crafter to try to apply more and more engravings and discover new combinations. So what do you think?
