There's no direct machine like the Elevator in the Mines but there are ways to make descending into Skull Cavern fun... -ish. See below.
Since you want an Autopetter (because they're great!), I suggest you make Skull Cavern as least annoying as possible. For me Skull Cavern is focused on
fun and
treasure, which is a good match for getting an Autopetter!
Luck is very important
•
Daily Luck at maximum: "The spirits are very happy today!"
• 1
Lucky Ring, Forged into another or on its own
•
Lucky Lunch, I bring 1 and eat it just before entering. When it wears off late in the day, I eat one of the inevitable
Spicy Eels the Serpents drop.
Other
Buffs are very helpful
•
Espresso or
Coffee for Speed, 3 Espressos is better as Coffee (~10) wears off fast so it demands more attention which I simply do not have
•
Slime Charmer Ring, this more of a personal opinion. I mentioned fun above and this ring is
key for my fun as I can ignore Slimes entirely to focus on actually dangerous monsters. This again is managing my attention span and minimizing distractions.
•
Mining Mastery. If you've opened the Mastery Cave, consider choosing Mining as your first power as 2 of the random Daily Buff options are
Immunity to Bombs (this is the
BEST!) and
Greater chance for Ladders and Shafts (clearly very useful).
More stuffs:
• Good
Weapon:
Galaxy Sword for now, Infinity Blade much later
• Good
Boots:
Space Boots now, Cinderclown Shoes or Mermaid Boots much later
• Good
healing Food, I use
Cheese as it's very easy to make (1 happy cow + 3.3 hrs in a Cheese Press gets you 101 Health!). Take 25-50, eat at half Health or even higher. Cheese is cheap, your Health is more important!
•
Bombs for clearing out large veins of Ores and Gem Nodes, I take at least 30 early on and closer to 100 when I get lots.
•
Staircases for quickly descending to ~Level 100 before Bombing. I take at least 100 for starters though in later game I take about 250.
•
Iridium Pickaxe. Gold Pick is
probably good enough but for those few times you need to break crowding rocks immediately, you want FAST
• I leave everything else at home except maybe my
Return Sceptre, but really: falling asleep in SC incurs minimal penalties, just stay 'til 2am to maximize your fun! You're there for LOOT and that means starting with empty pockets.
OK this is a big list but why?
Most important is Luck as that gets you MANY Treasure Rooms, in addition to the guaranteed ones on Level 100, 200, 300 and beyond. I usually get at least 10 on each run to about Level 150. Treasure Rooms are the point of this whole thing. You can get cool stuff like Autopetters, Animal Crackers, Prizzy Shards, Trinkets, Saplings, and Seeds. Yes,
SEEDS!
On the way to Level ~100 I just Staircase down, stopping for the Treasure Rooms. Past about Level 60 you may see increasing veins of shiny Ores or Gem Nodes, I Bomb them if I feel like it and there aren't too many monsters around. I ALWAYS skip levels with many Flying Serpents, I don't care what Ores/Gems are there. They're no fun and I'm there for
fun. ...and treasure but fun first! Fun fact: treasure is a subcategory of fun. Around Level 100 I start inspecting the levels more closely and if it feels safe enough, I'll Bomb the Ore/Gem Nodes and collect the shinies.
Repeat until 2am!
