The answer isnt always spiders there are other units available to lich sure the spiders are staple for many reasons and yes their ai is atrocious i wont lie but ive honestly cut spiders from the line and used t9 bronze acolytes that i got from mummy cheesing pve camps and it performed better than spiders. Fiddle around with skellies sure they get bad reputations but the unit themselves are pretty good i was suprised when the acolytes did that much better than spiders did but then again i rarely use them other than for pillaging. And no i dont have any divine items im waiting to see how big of an impact they bring but even before that i know for a fact magic stacked vega is insane plus getting command 30 on both avalon and virion is vital. Just experiment with skellies the main drawback of them is death but everyday you can go in there and maybe thats the change you need from spiders to push you into the perfect you need... potentially, anyways i know every lich and their mother runs scorp spider but maybe scorp warlock/occultist is what is needed not the spiders.
And hell maybe the answer is gold spiders behind occultists with heroes tanking who knows can only experiment with so many combos every week
It seems that you haven't been paying attention to your own race to say that there are other
units aside from Spiders. No other units does a faster job at killing aside from Spiders and all other units of Lich has no morale increase to speed things up even if you apply Lv6 War Horn from Avalon, the speed is still not enough I tested it.
Let's not go to Acolytes they hit fast but there's not enough burst damage to do it faster and their movement speed is like moving through molasses, you expect them to reach through the backline under 15 seconds? Dude, you're giving me advice to use T9 Bronze Acolytes, I normally keep T11 Silver Occulists for my looting and I've tested them, so let's not go there.
All the skeletons walk, and to tell me to experiment on a 15 sec timer is a pure joke. And stacking magic to Vega is the last thing you would do if you're after faster kills as a Lich player. I'm stacking magic on my Cleo and I know how to use her magic(in-case you try to teach those little steps again) and it's still not enough.
See what I mean, you keep saying things but you haven't tested it, stop giving blind advice. Wait, you mentioned heroes tanking? Are you seriously going to give morale boost by sending your heroes to the front and if they die, you can't cure them for the next 20 hours? I can't believe you're at 59 with that kind of thinking. It seems that you haven't encounter the Gold Horse Archers at 50~59, they would rip through any of your heroes like paper. I think you're just keeping this conversation up to scoop some advice, let me know if you need some, you can ask directly.
Please stop jumping from one conclusion to the other, Gold Turtles, Item Stats, now Skeletons? What's next? This is quite amusing to be honest.
