Skilled to the Core

This is a personal list of the skills I think are most useful in hardcore. There are two tiers. "Essentials", which is the best/must-have skill from every class and "Cool", which is the two runners-up. The ones marked with a *, I already possess. Those marked with a +, I only have gathered in softcore.

Essentials:
Amphibian Sympathy (TT)+
Eye of the Stoat (SC)
Pastamastery (PM)
Advanced Saucecrafting (SA)
Mad Looting Skillz (DB)*
Moxious Madrigal (AT)
Powers of Observatiogn (G)+

Cool:
Armorcraftiness (TT)*
Empathy (TT)*
Super-Advanced Meatsmithing (SC)
Tongue of the Walrus (SC)
Springy Fusilli (PM)
Leash of Linguini (PM)+
Elemental Saucesphere (SA)
Impetuous Sauciness (SA)
Overdeveloped Sense of Self-Preservation (DB)
Crossbow Fever (DB)
Moxie of the Mariachi (AT)
Fat Leon's Phat Loot Lyric (AT)
Gnefarious Pickpocketing (G)+
Torso Awaregness (G)+
Chronic Indigestion (Misc.)

Now, this list is, of course, debatable and mostly based on what I currently think, rather than know. Mostly with the runners up. Some might find that Disco Face Stab is more useful than Crossbow Fever. Others would like to see a damage-dealer included, because that would help the AT's, who have none of their own. Or they think that a different healing spell from the Tongue of the Walrus should be in there. That's mighty fine, and might even be true, but this is MY list.
