I've searched around for how spiritbonding works and can't find all the information I want anywhere, so I did some testing to hopefully make this a useful guide.
Tests were done with HQ 690 (Lv. 100) gear at BTN/MIN level 100. The basic methodology is monitoring the materia extraction window while counting gathering actions.
Here are the findings:
- The base rate of spiritbond gain was around 0.64% for Unspoiled and Folklore nodes, around 0.11% for Ephemeral (sand) nodes, and around 0.04% for normal nodes.
- The above gets a +20% bonus for each materia in your gear slot, making it 2x for fully pentamelded gear. The bonus is multiplicative.
- The above then gets a +10% bonus for each Spir
