So I was hoping to have my level 1 PCs fight a pack of wolves, I'm attempting 3 PCs, and I'm a bit confused on how I'd apply the young template as it'd drop their CR to Zero? I was thinking four or more wolves, but of course they're CR 1, 4 wolves would be a CR 4 vs the APL of 3 (Or two, because I minus one?).
I was hoping their was some kind of guide somewhere for CR Adjustment, or how to dictate a CR based on skills and abilities gathered as I eventually plan to make my own creatures but as a brand new GM would like to just modify what's there, and add or remove skills and move CR as needed for it (In this reference I'd like to add a negative energy effect to one of the wolves, after reading over Hallow's Last Hope I noticed it was built for a party of 4 level ones, yet the Magical Beast Worg boss was only CR 3?
Sorry if this is in the wrong section... Had a hard time defining where I should post this. Technically a rules question, I suppose.
