Spellcasting Ability Modifier
For both Fighter and Rogue I tested the DC for Drow Poison. It appears to be a minimum DC of 13. However when a Rogue/Thief or Fighter/Champion has a high enough INT score, the DC will be 13+ and use the INT as the spellcasting ability modifier to calculate the DC. This indicates that both Fighters and Rogues have a default spellcasting ability modifier of INT, regardless of subclass. Note that the spellbook will not show a spellcasting DC or ability modifier for these subclasses. I appreciate further testing and validation, as I only used Drow Poison and there are other items that inflict conditions using the spellcaster's DC. I was not able to use either STR or DEX as a spellcasting ability modifier under any of my testing scenarios.
Note - further testing shows that the above is a display bug which I've reported to Larian. The DC for Drow Poison is fixed at 13 and the calculation shown doesn't add up to 13. I was able to reproduce the bug with other weapon coatings. However, due to this display bug, the chat box does indicate that the game considers INT to be the spellcasting ability mod for all subclasses of Rogue.
