the skeletons are not there to fight for you. There is no viable way for that to work from the mountains forward, maybe plains forward if you have high defense staff ability.

you work together. freeze the enemy, so its slow. Help tank, since you are smart enough to block and dodge. They take a hit or two but prot staff keeps them alive.
all this works so much better if you leave ML and go level up your magic on trash until all your magic skills are 50+.

Even with the above..

I have found the mage armor and foods to be too much liability. What I do is keep going as a melee viking, and replaced my stamina food with an eitr food. Then I can freeze and nuke a little and cast protection on myself, but can't get these guys out because of the 2nd food requirement which leaves you weak.

the problem isn't seekers, really, those are actually kinda weak. Its the groups & swarms esp inside mines esp at the door first time inside. The skeletons will split up and get killed, and hardly slow down the enemy at all, or get cornered and stunlocked or worse get in your way. One seeker should go down to the 3 of you so fast it wasn't even interesting. Sometimes the bow guys are better, you can butcher knife them and retry until you get 2 shooters.
