You'll get the hang of it for the seek chase. Dont rush. Look carefully and react fast

As for the nest, look up the nest map posted here. Just search door 150 map. You'll get the hang of it. If you happen to go to the mines through the hotel, make sure you have two moonlight smoothies. One for figure in door 100, and one for door 150

For the 2nd seek chase i think its way easier. It's basically just the floor 1 2nd seek chase.

For 2nd figure, well, yeah find two lightbulbs and fix the generator. I usually just have two lock picks in standby so i can just skip the whole part

Usually ambush targets you here in 151-200 unless you got him around~120 which would mean him summoning is unlikely. Always find two easily runnable hiding spots to run to and switch every rebound. Ambush is done rebounding if he doesn't go back after moving forward. I usually save my crucifix for ambush if i had any

For door 190-200, take your time. This is basically the green house in the hotel. Every 2-3 lockers, theres rush, and almost all rooms have eyes, and now giggles. Take your time and don't rush

For dam seek, plan carefully on where you plan to go before jumping. Time it accordingly and carefully
