Why do my spectres keep getting one shot?

TL;DR: is there any way other than minion life and damage nodes/gems to scale spectres?

I'm currently running a raise spectre build with Tukohama's vanguards. I have Tukohama's fortress, with Necromantic aegis. My spectres should be pretty tanky, as I took almost all of the minion life nodes, as well as TF + necro aegis. However, when I attempted Minotaur, all of my spectres died in two melees from the boss. Even if I took every single minion life node, they would still die in 2-3 hits. I re-summoned them in the instance, so they were all lvl 83. I don't know what other way there is to scale my spectres. The character is only lvl 75, but from the way I understand it, your character level/stats have no impact on spectres. pls halp

Minion leech and resists basically.

THe minion life nodes on the tree are not as important. Take the minion leech and regen nodes instead.

Now resists are the most important thing to keep specters alive. You have two options with TVs:
1) Put Minion and Totem resistance in your 6L (decent option if you also use a single wicker man as this boosts his damage too).
2) Have minion resists on basically every jewel. I would lose the unending hunger. You just don't need it this league because of how much better abyssal jewels are.

Get yourself abyssal jewels with Life + minion res + taunt/blind/regen/leech in all your jewel slots.

Take a look at my char Myth_Specters_Abyss. My TVs have literally died to nothing except shaper so far (ilvl 84) and they are on a 5L still.
