Using non-mechanical descriptors from Pathfinder SRD for a non-d20 system game


I have an inquiry. If someone can help me with it, I would strongly appreciate it.

I’m currently in the process of designing the bestiary of my TTRPG. It doesn’t use the d20 System, but I’m taking creature concepts presented in Open Gaming Network sites, more specifically: name, size, alignment, combat actions, environment, and organization entries, from Pathfinder 1 SRD, and Dungeons & Dragons 3.5 and 5 SRDs.

My concerns are related to where my limits are, if any.

  1. How should I proceed if I’m interested in taking those elements of such SRDs?
  2. Would it be wiser to take some of those elements as inspiration to make my own version of those values (environment and organization)? If so, would I still have to make some legal move?
  3. Would it be wiser to just take from one SRD?
  4. Is it safe to take Open Gaming Network websites as part of the SRDs?
