9. Utilize Minion-Defensive Gear
Minion-Defensive Mods on Gear: Equip your gear with defensive modifiers like Minion Life, Minion Resistances, or Minion Damage Reduction. Specific items like The Vertex helmet can give a significant boost to Path of exile currency minion survivability.
Flasks: Use Granite Flasks or Jade Flasks for Physical Damage Reduction or Evasion to keep yourself and your minions safe. Life Flasks for yourself and Divine Flasks for instant recovery of health can be invaluable in critical moments.
10. Focus on Boss Mechanics and Avoidance
Learn Boss Mechanics: Understanding a boss’s mechanics and the phases of their fight is crucial for positioning your minions properly. Avoid standing in damaging zones and constantly reposition your minions to prevent them from being in the crossfire of boss attacks.
Manual Dodge: While your minions can’t dodge, you can! Kiting and buy Path of exile currency keeping the boss distracted while your minions do damage can save you and your minions a lot of headaches during high-stakes encounters.
By upgrading your minions’ defenses, utilizing Life Leech, and improving their positioning and movement speed, you can keep them alive longer during boss fights. It’s also critical to learn the boss mechanics and position your minions accordingly to ensure they don't die from AoE attacks or specifically targeted mechanics.

Using a combination of these strategies will greatly enhance your minions' survivability and help you take on the most challenging content in Path of Exile!
