I Just beat Salamander and I have to say Gnome is the MVP.
I mean a good number of Monster Girls in Chapter 3 have the "Use Gnome to escape grapple, use meditation, GG." as their strategy. But I especially love when during the Dragon fight the game explicitly tells you to use Undine but laughs at you the second you don't use Gnome, oh or in Salamander's fight right after you awakened Undine's power. Nah you haven't actually awakened that power yet even when that explicitly happened in the last fight, you gotta use Gnome until Salamander tells you Undine is ok, then you win.
