What should I imbue for my points

I am doing the nightmare zone and I have 1950000 points. I am a meele slayer, what should I imbue? Berserker ring and slayer helmet?

 

Imbued slayer helm would be pointless for you as its for mage and range I'm pretty sure it provides an extra 15% boost to ranged accuracy and damage, and a 15% boost to magic accuracy and Magic damage. (Information from rs wiki Slayer helmet (i) )

As for the imbued berserker ring it provides double the bonuses of a regular berserker ring which would benefit you.

 

Ok so the only good I can imbue is berserker?

EDIT: When I got requirments for zulrah I will go there so then slayer helmet or salve amulet is good for zulrah?

 

For melee slayer yeah would cost you 650,000 points i think.

 

you should still look to imbue all rings + slayer helm. If I were you I would continue nmz until your 90/90/90 and imbue everything to help with slayer efficiency.
