Living Wall
Living Wall is an Act 1 event where the player faces a wall that forces a choice between three magical options: the wall can Forget (remove a card from your deck), Grow (upgrade a card in your deck), or Infest (add a random curse to your deck). Only one option can be chosen, and the wall decides the order in which the options are presented.
Living Wall's value heavily depends on which option is offered. Forget (card removal) is generally the most valuable in early Act 1. Grow (card upgrade) is also excellent if it targets a key card. Infest (adding a curse) is the worst outcome and should be avoided if any other option is available. Players sometimes skip the event entirely if Infest is the only or primary option being offered. When Forget is available, it functions as a free Purifier and is nearly always the correct pick.
