Elgyem has a rarity and “required effort” comparable with pseudo legendaries, some rare starters and other popular Pokémon. That is problematic! Rarity is a way to keep people going back to the dungeon, but in this case it’s about Elgyem! An easily forgotten Pokémon from gen 5, and so a rather strange one to function as “the one worth going back to CCh for!”
Wikia says, Elgyem has a Recruit Rate of -3 % on floors 56 to 60. (Also, as you may have guessed, the spawn rate is not high at all). It’s requires significantly more effort to find Elgyem compared to “not really super popular” Pokémon like Klink or Sigilyph, since you need to go 56 floors to get there and only spawns on four floors. Also, there is perish song in these floors, and 8 inventory slots are occupied with letter stones, key and tablet instead of potential honey.
I suggest Elgyem should have similar rarity as Sigilyph and Klink. One way is to give Elgyem the same Recruit Rate as Klink, 1 %, and have it appear on all floors 51 to 60 (just like Klink on 41 to 50), with same spawn rate as Klink as well. Other suggestions welcome!
A change like this should not make CCh suddenly lose replay value. It’s hard already to find Klink. Mewtwo drops Golden Masks and Gold Silk chamber is on F50.
With appropriate rarity of recruits, effort put into these Pokémon will be used to the potential it has, and players can enjoy, without a disproportionate price, all we offer!
(edit: after discussions, I think the recruit possibilities does not need changing, not sure if making edit is the way to go, but ah well, better than posting?)
