Ok, so I summoned a Ice Devil finally. Equiped him with wraith blade, bone armour, winged shoes, ring of regen and amulet of luck.

First battle he enters against an army of infantry and a mage. Paralyzed. instantly dies.

MR of 19. Im hoping that it was a big fluke.

It can happen to any SC, even with the best equipment. You can give it lower risk assignments (e.g., capturing provinces with low PD, having it fight alongside an army), or you can just create more SC's. In my opinion, the SC's mobility is more important than one-man-army heroics.

Did you have him buff with Quickness and Breath of Winter? BoW will help even when the SC is unconscious. Bone Armor is low protection, and the Wraith Sword already gives you life drain. Try something with higher protection, such as Marble Armor. A Starshine Skullcap would be good since you can never have too much MR. With lots of Blood, you could give him a Blood Thorn, which would free up one hand for a shield -- Charcoal Shield is my favorite.

and if you need a pure def shield go for accursed

Well, my reasoning on the armour was that
A> You can never have enough life drain.
B> Its AE so for one man army heroics when hes surrounded and his def is quickly nullified hes still draining around him

I had him casting quickness I wasnt sure BoW would stack with his chill aura.

If you lost a SC to Ermor AE, it's because relying on life drain items is a big mistake. (I thought you said in your first post that you had handled Ermor easily and were floudering after defeating Ermor.) You can't life drain from lifeless units, such as most AE undead. Most undead are also resistant to cold, so an Ice Devil isn't the best match (though it should do fine with the right equipment). Herald Lance and Charcoal Shield are good, or you can go with the double-handed Flambeau.

You shouldn't rely on a single set of equipment for a SC. You have to know the best equipment for the situation.

if you want something quite cheap vrs ermor then use (as said) a charcoal shield+herald lance on something flying(winged shoes on it if it cant fly)
golems are really good for this with their self buffs and something like jade armour will help get those buffs done quick.
and of course if he summons any big nasties or if you need an sc killer a golem with a gate cleaver is pretty good.
for any golem i would suggest ring of the warrior and a defence increasing item for misc slots
