Tektite
If it's just a physical property, it's particularly easy, as most of it has already been solved in TOTK.I don't know if they can solve the problem of lack of item functionality, the common problem with TOTK and BOTW is that if the whole system is completely since the physical chemistry engine, then it will result in a lot of homogenization of item props use, I hope they can design more functionality for each item then combine it with physics to use it.
But once designed for a special purpose, there is still a long way to go. Unless they can achieve the feat that they did in TOTK.
The way I can think of to solve this problem is to digitize temperature and other properties, but this can lead to the game being filled with annoying mathematics.
In addition, they can only design special effects for each item, which will result in an exponential increase in workload.
