Between wands and scrolls, I had all the magic I needed. Priorities are escapes such as dimensional swap or sanctum, any insta kill spells, and any spells that can kill out of line of sight (insect swarm can chew through multiple monsters around a corner).
The tediousness is the size of the level. The last few were ginormous, and I shudder to think how long it will take to walk through say level 120. The last few levels I had to zoom out many levels to manage the map. This kinda works to my advantage with god of secrets (the only god that scales with the level size), however, with all the guaranteed damage dealing from the pit traps/fire traps/poison traps, that do a TON of damage, I had to sit out hundreds of turns to regenerate my health. If I needed food it would be GG right there once the herbs run out. With high energy I can trigger multiple traps each turn, so the limiting factor was not energy, but health. I think it is a problem with this build, since it is meant to explore every corner of the dungeon to find secret doors. Once stat cap was reached, I hit diminishing returns, and so had to switch to getting through the levels fast.
The problem was especially bad on the starry astral special level full of mazes and teleporters. I had to keep good track of the teleporters and where they led, and started dropping herbs as a breadcrumb to mark ones I have explored. It took a great deal of methodological exploring to finally get the right sequence of teleports to arrive at the exit stairs. This made me very glad the staff shows up earlier, because if this level showed up later, the exponentially complicated maze path would be quite hard to solve. This is a fun level at say level 20, but at level 80 it became depth first search on a large scale, but with teleporters.
The first few levels, especially my run up to the first special level, was not tedious at all, and very fun.
Most other builds are meant to find the nexus/santum asap, get their bonus, then go to the stairs and rely on some sort of magic to allow them to find and beeline to the stairs. With this build, it is walk, trigger every pit, eat some herbs/wait, walk, more traps, wait, wrong way, let's backtrack, darn I have to step on all these traps yet again.
My hardest fight was my first special level, which was hell/gehennon again. The hell knight somehow spotted me, so I backed up, paused and checked my inventory. I had picked clean the previous levels, so any items or stat boosts were gone. I hit him with blind but he resisted and blasted me, but I got him with the 2nd blind, then used poison arrows to shoot him down. My 2nd blind was also my last scroll that was relevant, and I was too weak to trade shots with him and since he regenerates fast I could not even hit and run him to death. I got really lucky that my 2nd scroll of blind landed.
I had a much harder time in my savescummed build which had necrophobia, because the undead are common and powerful, so created many dangerous areas I had to bypass. With this build, only invisible creatures gave me issues. Any aware creature I waited out of range to regenerate energy, then smacked him with multi hits (I could squeeze in 6+1 hits with max energy) which usually did the trick. I think necrophobia is a valid pick for fighters or mages who never rely on sneak for the most part, but the penalties are steep for thieves/rogues.
I used to swear on critical hits, but with all the big monsters being immune to crit, I may think again about picking it.
One aspect of the new faster staff generation seemed like the AOD did not seem to appear. Maybe it did in a corner, but I never ran into it (and I think you have to run into it, since it is invisible as well). In the old versions you will cry if you see it on the stairs, and you are out of rope. Maybe it has more of a chance to show up in deeper levels.
Going to see if I can win in fewer turns like Max's runs, maybe a no mana bard build with hunter. I had prior success in this LabyDX version with this, almost felt like farming. You find a rat or easy animal, maybe even trigger it to call reinforcements, kill other monsters, then let it take over the level. Then kill what you needed and eat the drumsticks/ham, return when necessary to harvest more meat, while bardic magic can get you regeneration eventually. As for water, bring 5 skins, and walk into a lake.
My closest prior victory attempt was in the old Frank Malota version where Scroll lore meant you could learn spells, so I picked that, and no other magic picks, and eventually amassed an arsenal of great spells, which combined with infinite nexus use got me very far.
