You can *beat* Hell with almost anything, but "HC hell" with "no sweat" and "shopped items"
Not saying its trivially easy or that anyone with no idea what to look out for could do it, but its pretty obviously one of the easiest if not the easiest builds to HC on. Spend a lot of time on players 8, you can get to like level 40 before finishing normal and 60+ before hell if you want.
re: items
Buy a wand with +3 summon skeleton in act 1 normal. You could theoretically get +3 summon +3 mastery but that'd take a lot of time.
Run countess a few times. Socket Stealth runeword for more movement and throw the +fire resist runes into a helm to max the most important resistance.
Act 2 buy decrepify wand as your offhand for bosses.
Act 3 buy teleport staff
Act 5 socket the +resistance runeword you get for free
A few more +resistance from jewelry/gloves, some decent FR/W boots help. Around level 50-60, whenever it becomes available, shop a +2 all skills or +3 summon skill wand that'd be good. Only really powerful item that is purely luck-based would be an offhand with +skills good enough to replace your +resistance shield (EDIT: you'd probaby want a non-magical 2 socket shrunken head with +skelli bonuses to put shael-eth in, but this is the kind of thing you could easily find in act 1 normal or never find the whole game, or just find a really, really good magical one). But basically all your essential equipment needs could be fulfilled before nightmare, aside from a high-damage spear for your merc.
(all while maxing CE and using clay golem to "stomp bosses"
) is funny af
Not maxing CE is idiot-tier. You wanted to max skeleton mages and revives, lol. Both of those are complete and literal trash to put more than 1 point in.
Decrep + clay golem speed decrease basically breaks bosses AI with how slow it makes them. IIRC baal won't clone himself and other shit, because by the time the longer-cast abilities are half way done the AI almost always decides to interrupt and do something else.
