Maces are pretty universal for swamp, except abominations. Which then you just use your axe for something other than chopping trees.

For mountains iron mace is best as it will usually stun wolves on the first swing and kill the second. Swapping to the Frostner in mountains is a horrible idea because the golems take less damage from it than an iron mace. Although a Porcupine later does work well.

Frostner does work fairly well in plains because it slows the fulings down on first hit, then it is easy to flank them for the other hits.

As for multiple wolves giving you a hard time,most of their power comes form fast staggering attacks, which even in fully upgraded wolf armor you get staggered frequently if hit .
