PoE Righteous Army, Cold builds

Hey guys! I love theorycrafting and the new gems and items have given me food for my curiosity, this time around I decided to create a build with intuitive link based on minions. Here's my concept: I like how Discharge plays out, so I wanted to include it in this build. It's also a convenient spell to pair with the rest because you don't have to cast it regularly, saving you from mana issues you would have due to Intuitive Link. So I want minions spells and charges, best ascendancy to pair all these is Guardian. Next, I need a plan. How am I going to generate charges for Discharge reliably? N

the idea here is to have a full army of animated minions, getting layers of % of phys damage as extra cold, and then converting the phys damage of minions into cold in order to abuse hatred's more cold damage buff. Dps seems fine enought, but the problem seems to be gathering the animated weapon army on boss fights, as you need to raise lingering blades first, so that they raise animated guardian's weapon on hit. Also, you don't have the full dps on bosses, as some of the animated weapons count come from the "on death" ani
