How do i get berserker helm (i)?

How do i do this?
I heard the bonuses are great, and i think its something to do with mobilising armies...But im not entirely sure.

Please help.

 

There is no such thing as a Berserker Helm (I) there's only a Berserker Helm (E) or Berserker Helm (Charged)

 

I think he means berserker ring (i), which has double the bonus of regular ring. mobilising armies, for about 25 horus of suicide training

 

I'm pretty sure that helped him, it helped me a lot too, never knew about thaat!
As to the helm, there is only (e) and (charged).

 

I meant (e) helm not (i), but thanks for helping about the ring too!
I take it the helm is the same as the ring?

 

You get the berserker helm (e) by enchanting it with Pulpix the summoning guy (I think that's what his name is)
