Always keep a torch lit so you don't get sniped from the darkness.
You should be able to dodge all Evil Eye deathgazes and Scorpion attacks with a rogue cloak +10.
Use scrolls of magic mapping and potions of mind vision in demon halls to quickly locate the Demon Spawner so it does not have time to spawn too many Ripper Demons.
Smoke bomb for Rogue tier 4 is a good way to dodge Evil Eye deathgazes if you get caught off guard.
I think i never went under 100 hp during Yog fight as i was healing like crazy thanks to the RoA and vampiric enchantment combo. I had a spare RoH+1 at the time i went for the transmutate.
I had the same feeling until i started to go for the 6 challenge badge and the million score badge. Now i have all of the badges and even won an 8 challenge run. Only thing left is to beat 9 challenge run and i have been attempting that almost weekly. I've been pretty close a few times.
This is the dumb everyone learns the hard way. π
Another dumb is trying to move and not wait out vertigo from confusion gas trap making you fall down into a chasm and dying to fall damage.
Had a really nice start today but got the horn of plenty too late.
Just noticed i had a scroll of mystical energy there... could have filled up the horn with it a bit and made it. Well you always remember stuff too late and always learn something new every time.
Now time for the ultimate test of 9 challenge. I was so close a few times but never have i held the 9 challenge amulet. I still attempt almost every other day. Good job on the 8 challenge that is no easy feat.
I think you can get away from the crab here by taking only like 2-3 hits from it.
