Extra toughness on a curio might sound tempting, but as it stands, it’s actually a risky choice.
The risk comes from the presence of the “% of missing toughness bleed-through damage” mechanic. While having more toughness means you have to take more damage to increase the bleed-through %, it also works the other way.
Having more toughness means you will take longer to recover back to high toughness %, meaning you’re more vulnerable to increased bleed-through damage for longer than someone with a lower max toughness.
This is especially unfortunate because there are an assortment of things that happen in the game that delete 100% of your toughness, no matter the actual value.
This means if you have high toughness, things like fire straight-up deals more damage to you.
The presence of the bleed-through mechanic means that the bonus toughness stat is not really a wise choice to take.
The bleed-through mechanic is important, but I think it needs changes.
I believe if bleed-through only starts when you are at a specific value of toughness, not %, we’d be in an okay spot. A change like that would mean that extra toughness will always act as a buffer, and never come with a significant downside.
In the end, I think something needs to change in order to make extra toughness actually mean you get tougher.
