I thought that the stipulation that 1st level mods could be replayed with different characters would also apply to GMs taking credit for running first level modules, but going over my GM sessions I noticed it brought up applied credit errors. Is the error erroneous ? Or are players allowed to replay that as much as they like , but GMs can only get credit for running it once ? ( like gods mouth heresy )
For Tier 1 (not 1-5 or 1-7; Tier 1) Modules and Scenaios, a GM can apply the credit from such a session to a different 1st-level character as many times as they have run it. The only caveat is that a GM can only apply credit to a single 2nd level character ONCE. After that, it's either 1st level characters or foregoing credit. At least that's my horribly sleepy understanding of it. The 1st level character may or may not have to be new characters; I couldn't give an answer on that in good faith.
