As the title already said I'm needing help understanding how to make the build like the guide says, i somehow need to get the full set bonus of bones of Rathma but i also need the full Captain Crimson's trimmings bonus for cd reduction i can get that with ring of royale grandeur but i also need to use fate's vow helm but if i use it i cant get the full Bones of Rathma set bonus or Captain Crimson's trimmings bonus. 
If anyone know how i can get that build to work please say how, I'm open to any suggestions.
Link to the guide I'm  talking about: https://www.icy-veins.com/d3/necromancer-rathma-army-of-the-dead-build
(this is my first post on icy-veins and i don't fully understand if I'm doing this right) 

Raid/Class Spots Are Open To Any Applicant If The Player Is The Right Fit
A guild formed with an ambition for progression and a love for M+ we decided to make the move from Silvermoon Alliance and form a guild to take our focus to the next level, Cutting Edge in 10.1 being the next step.
We believe in building a guild by recruit players of a similar goal and mentality whether it be for raiding or for push score in Mythic plus. We value loyalty, honesty and a positive attitude towards setbacks. Communication skills are an absolute must.
Raid Schedule
Wednesday 20:30-23:00 Sunday 20:30-23:00
Current Progression
9/9HC 5/9M
What are we looking for recruitment wise?
We're currently open to recruiting DPS classes listed above, as we aim to solidify a stable 25-player roster. We're looking to provide competition to existing members and choose the best 25 players to proceed with for next tier.

Hello everyone,
Last patch gave us 40% and 10% damage increase on ray of frost and glacial spike
Does anyone know of these changes make them relevant ?
Should frost mage play with these or one of these now ?

I am going the corpselance support build for Necromancer and the build has me taking Corpselance with Brittle and the pestilence set on top of that, if I were to take off the ability Corpselance and change it to another ability say for example Bone Spikes with Frost spikes, would the damage decrease an amount that it would not be worth it?

Casual | Alliance | Whitemane |  Loot Council | PST
Casual is an established Day 1 Whitemane guild that is recruiting for Naxx, and looking for competitive players to fill our TBC roster. 
Guild Goals: 
Compete with top guilds in TBC.
Never Miss a Lockout
Clear Content Fast and Efficiently
 
Recruiting:
Sunday/Monday 5:45-10:00 PST
Fury Warrior
Holy/Disc Priest
Shadow Priest
Fire Mage
TBC Recruitment is going to be open competition for raiding spots.  There will be an alt run, and the guild will be hosting GDKPs.
RESTO SHAMAN REROLLERS NEEDED!!!
Expectations:
1. Come Prepared.  The content is 13 years old, there is no reason to not know the mechanics of a boss.  We will post Strats and info graphics prior to a raid release, but it is the raiders responsibility to understand the Mechanics.   Bring your consumables, there is no excuse to not have your flasks/Potions/Food for any given week.
2. Be open to criticism.  No one is perfect, and we expect anyone in the raid to be able to handle being asked or told (respectfully) how to do something better.  We will not tolerate any kind of childish behavior, the raid comes first, and no one is above it.
3. Perform.  With all the resources available to the player base today, there are few excuses to not know how to play your class effectively.  We expect raiders to have a knowledge of the class they play, and be able to absolutely pump in whatever role they are filling. 
Loot:
Casual has been a loot council guild from Day 1, we have a public spreadsheet that tracks where every single piece of gear has gone.  Factors for the Loot Council include, but are not limited to:
Effort
Attitude
Performance
Raid Benefit
