Playing my third playthough of Stardew with the Adventurer's Guild mod

Midway through the mod's storyline you have the option to save or kill a pink slime. And by glancing through the CJB Item Spawner I can see that killing the slime would ultimately get me a different set of items (without having to cheat for them, I mean), plus saving the slime ultimately leads to a very strange gap in the storylogic of the rest of the game...

but I just can't bring myself to do it. Round three, and I guess that the other storyline will go forever unknown by me!
