Essential and Situational Items

I dunno if someone has already made a post like this but I was wondering what you all consider as essential items to carry around on your adventures. I just wanted to see some suggestions to see if I have missed any useful ones. The items and equip that come to mind are:

Essential
HP Potions (I use onigiri cuz I'm cheap)
MP Potions (I use dango because I'm cheap x2)
Antidote, paralyze heal, eye drop, moist dirt, tvorog, tear of the moon
Vaccines (Poison, paralysis, blind, freeze, sirok)
Veltria on an equip (when not using a healing class)
Resist gears (In case a rogue chako sneaks up behind you)
Damage gear (On the off chance that chako doesn't hit hard)

Situational:
Crystal Hammer (when losing aggro)
Sofys Shield (when using immortal set or when out of MP Potions)
Cracked mage ore 
Strengthening food items
Elemental drinks (to flex on the plebeians) 
Brave shield (I dunno if the autoskill can cure all ailments and I've never tried to see if it works)
MPC gear
Unread fortune

If I missed any, feel free to share some of the items and equips you deem essential or situational!
