Does having more wolves in a hunting party increase their odds of success?

Title.

Is a hunting party of 5 more likely to catch their prey than a hunting party of 2? Or is it strictly for energy management purposes?

That would be the case, yes. Hunting success is linked to party synergy (personality clashes and proficiency matter too ofc). Every wolf is adding a max of 20% in synergy when maxed out, so having a full party will eventually lead to a team with 100% synergy, therefore making them more likely to take down prey.

This guide has a more in-depth explanation about all aspects of hunting, including synergy and its affect, it is worth a read!

Thank you so much! I actually have read through that guide, but completely missed the mention of each wolf being able to contribute 20% synergy. That completely answers my question :)

No problem! It actually follows this formula (WS + WS + WS + WS + WS / 5 = Party Synergy), it isn't directly mentioned. But if you consider that a wolves synergy is max 100 and you replace that in the formula with however wolves you have, it comes back at 20% max. the only exception is a single wolf party, a wolf alone cannot gain synergy, so it'll always be at 0% :)

Is there any way to check a wolf's individual synergy level that it's contributing to the hunting party?

None that I'm aware of! Synergy isn't one of the things I have looked too deeply into to be honest x3 I would suppose it raises with every hunt a team of 2+ wolves have, so it'll scale somewhat with their prof levels, but I can't say that with 100% certainty.

Interesting. I'll have to keep an eye on synergy levels for sure :P
