I wrote down all the garbage I found in the next dive, with the level where I found it:
23 - Golden Animal Cracker
36 - 2 Iridum Bars
50 - 5 Spicy Eels
76 - 15 Cherry Bombs
92 - Auto-Petter!!!!
100 - Red Slime Egg
from here with bombs and without the +5 luck from the Candy
136 - 4 Quality Sprinklers
139 - Auto-Grabber
148 - Seed Maker
200 - 5 Warp Totems Farm & 5 Mega Bombs
After 200 I used only bombs and it got late.
So, I finally got the first one.
A few attempts later I found two in one dive to 300.
And finally I found 3 more Auto-Petters in a dive to level 404.
On level 400 was a chest, but that was probably just coincidence.
So now I have one spare and the next goal is perfection. :)
Seeing as
@jan_flying documented their experience getting the Auto-Petter here along with their list of floors they got Treasure Rooms on, I'll expand on a dive I just did. I didn't record each Treasure Room level as swapping between the game and a text file really messes with my (lack of) concentration, instead I'll have a summary and screencap every 100 Levels.
Conditions:
Medium High Luck day, good but not the best
1 Magic Rock Candy for
+5 Luck for the first 8:24
1 Lucky Lunch for
+3 Luck for the remaining time
3 Ginger Ales for
+1 Luck the entire time
1 Lucky Ring (Forged) for
+1 Luck
Rabbit Foot to Joja driver for that small Daily Luck Buff
No Luck from Statue of Blessings
So +7 Luck for most of the dive and +5 for the remaining time. If Daily Luck really is about +0.075 using the same scale as the above Buffs, that really doesn't amount to much.
So what happened? I got to
No! Stupid Snape always interrupting!
Level 394! My best run ever.
Thanks for ruining it, Professor...
By Level 100, it looked like this:
That's 16 Treasure Rooms, the whole bottom row (Iridium Bars is 2x) and the first 2 from the next (Sapling and Spicy Eel) plus 10 Bombs. This includes the guaranteed Level 100 Treasure chest. 16 is a LOT.
By Level 200 it looked like this:
That's "only" 9 more Treasure Rooms and yes the Magic Rock Candy and Ginger Ale were active the whole time. Just randomly worse Luck as none showed up until the late 130s. It's the bottom 2 rows minus the Scepter, Lucky Lunch, Iron, and Coal.
By Level 300 it looked like this (before opening those 3 Chests):
That's 10 more Treasure Rooms, by now the Magic Rock Candy had run out, replaced by the Lucky Lunch for a somewhat lower Luck experience, Ginger Ale Still active. Bottom 2 rows plus the Bean Starter and 1 more Diamond pair
By
page Level 394 we got this after I passed out at 2am:
That's 8 more Treasure Rooms, but considering this number also includes the 3 Chests from Level 300, that's only 5 new ones. So that extra Luck I had earlier seems to make a difference. Can't be sure until doing more runs but yeah I'm not gonna document that. Just load up on as much Luck and you can make/wear/eat.
I Trashed the extra Cowboy Hats as I have zillions of them but there were 4 total before removal. Yeah I kept the Tempered Broadsword monster drop as I couldn't remember if I had one.
I didn't have one, I had 5. Oh well.
So this was fun but note that with all this luck:
I did
NOT get an
Auto-Petter. More luck will not affect that drop so you just gotta do multiple runs, repeating the day if you want or going on successive days if you like the other loot and have the resources.
