I still get a grin when a horde of skeletons holds a choke point while I sit behind a life-stealing barrier and sip tea. For single-player RPGs like 'Skyrim' the best survival/utility combo usually comes from three kinds of mods: spell packs that actually expand necromancy, perk overhauls that make summoning scale properly, and follower/pet-control tools so your minions don’t stand in fire. Spell packs such as 'Apocalypse - Magic of Skyrim' (adds flavorful necromancy spells) and perk reworks like 'Ordinator - Perks of Skyrim' are great foundations. Then add a follower-management mod like 'Amazing Follower Tweaks' so you can dismiss, command, and position minions without being haunted by micromanagement.
I also lean on combat and defensive mods: things that give you better crowd control, reliable life-leech, or a personal shield spell. If a mod gives summons proportional health/armor scaling with level, that single change often makes necromancer play feel viable late game. Finally, UI and QoL mods (pet hotkeys, consolidated summon menus, and better target prioritization) turn a clunky minion army into a tactical force instead of laggy chaos. If you mod, pay attention to load order and compatibility patches—nothing ruins a perfect ritual like borked AI or CTDs—so test in short sessions and backup saves.
