For the ranger bonus wit the void knight gear do i need the gloves and stuff also? or just the bottom top and helm?

You need the gloves as well.

 

So Helmet, Top, Bottom, Gloves.

You need to have it all I'd think.

 

Runescape KB

 

 

If you wear a complete set of void knight armour (you don't need a mace for the set), you will receive a bonus 'set effect' depending on the helm you have chosen to wear.

 

 

 

Void melee helm: +10% to Attack and damage

 

 

 

Void mage helm: +30% to Magic attack

 

 

 

Void ranger helm: +10% to Attack and damage

 

 

 

If you didn't need gloves/seal, they would of wrote it there.

 

 

 

 

 

EDIT:

 

 

 

I don't think you need the seal, it's talked about seperatly from the rest of the armor in the KB article.

You don't need the seal.
