To reduced player dependence on library and spoilers chat, create a visual indicator on tower MM items. This could be unlocked with an item (eg. Tower Blueprints) hidden behind a Cecil quest or friendship level.
This is Pirate Banana's idea.
Problem statement: there are commonly overlooked MM items like Chum and Garnets that are technically easy to MM, but do take months. Getting blocked at a tower level for months is a bad experience, so folks trying not to spoil themselves often show up in spoilers quite cranky when they get to this level. It forces folks to read the library or look for spoilers in other places. This takes folks out of the game.
A quest from Cecil around T150 that warns the player about difficulty ahead and rewards them with an item to help plan MMs would be a better in-game experience. I could imagine a little tower icon in tower MM item pages, though I'm not picky on implementation.
