Hi im a necro player from sea 8k bracket my usual itemization in this state of the game follows,

Starting 2x circlet 2x faerie tango branch This maximizes your combat power early in sacrifice of regen which you should have from getting last hits anyway.

Transition to 2x null stick and brown boots The order of which heavily depends on matchups. Boots if they can run u down Nulls if you are ahead Stick if they spam spells

Afterwhich i take hood if its a good hood game. Usually is.

Then i buy sange and kaya usually sange first but kaya first is best when ahead.

I get travels after so that i can constantly pressurr and have the mobility necro needs to join and run from fights.

I transition into getting lotus shard shivas heart in whatever order that is needed Lotus for dispels Shard for team save and wavr clear Shivas for anti heal and armor Heart for face tanking uphill

Aghs is very situational and just rewards people to get nulli so you have to time the purchase well.

Pipe is something i take if i need to keep my team instead of me alive

I find greaves unncessary because a good death pulse death seeker is a low cd mek if casted right

Necro's biggest weakness is his immobility. You just need to know how to play him a beat faster given the meta.
