The Meeble thing is very complicated indeed, I still don't get why they had to go that way with up to 5 physical inventory space taking items that you need to trade to receive the pheromones, then trade back, then this, then that, blah blah.
It's very unfriendly and complicated.

Couldn't they have gone something more simple, linear and streamlined? You go to the NPC, if you have enough Pheromones he will offer the chance to take a mission. As you complete them you get a Key Item, once you beat the boss all the KIs disappear (kinda like Einherjar).
That's it, no inventory stress, no complicated trades that make you wonder "why do I have to do this?"


I suppose they went the grimoire way because they wanted you to allow to "farm" access to a certain boss more times, so that you could do multiple runs one after another, but was it really that necessary, I wonder?
