How to Exploit
Normally you cannot goto camp in the house of hope.
But… Just before you leave with hope, you can stealth around the room and stand behind the back pillars. There is no “hostile” zone there, so you can go camp and get a full rest.
There is a path outside the House as well. Can go from Haarlep’s room to a cave entrance which is a 2nd way to get down to Hope along the side and it counts as outside the red zone.
Although if you have access to Haarlep’s room just as easy to go in the pool and click the faucet to rest (counts as a full rest so get healing and spells refreshed). Can keep doing that the whole time there including after seeing Hope and before seeing Raphael.
