Pathetic Boots: The name, of course, is a euphemism.
Staff of Tranquility: A branch from a mighty, legendary, celestial tree, crafted into a magical staff. It has a small emerald in the shaft that doesn't do anything at all!
Omega Helmet: A helmet that was taken from Siluze. It may or may not have belonged to him at some point.
Crystal Mask: A shimmering helmet that seems to be made from an almost immaterial substance, which gives an impression of flowing water even though it's not actually, y'know, flowing. Or water.
Rogue's Hood: A stylish leather hood that increases speed somewhat.
Lucky Horseshoe: A horseshoe which is rather superstitiously said to grant its holder improved luck.
Ruby: Rubies are extremely valuable red gemstones, a variety of mineral corundum. They're mystically associated with strength, passion, power, fire.
Sapphire: Sapphires are corundum gems of any colour other than red, the most popular and powerful colour being deep blue. They're mystically associated with mind and spirit, magic, intellect, water.
Topaz: I just don't understand... why are topazes grouped together with rubies and sapphires... I mean, they are much more common...
Mana Potion: When consumed, this potion instantly restores half of your precious Mana Points. Or Magic Points, if you think they're called that. It also causes severe diarrhoea, nausea, hallucinations, and malignant tumours, but that's not relevant.
Keg of Ale: A keg of ale. You can't drink from it though. Why? Because. Shut up.
Santoryu: This sword is not copied of any other game.
Icy Crystal: A clear blue gemstone. It's probably magical. I mean, everything else is...
Zyl Orb: If for some reason you feel like Aero did a bad job at setting the stats of our heroes, here's your chance to adjust them to suit your needs.
Magic Dust: Information can be extremely valuable. With this thing here, you'll be able to see nearby invisible enemies! Information has a price, though...
Restoration Potion: Genuine restoration potion! Whoops... I'll just remove this made in China sticker... Doesn't belong to this item, obviously!
Soldier's Set (3): This is your regular equipment... on steroids. Alright, alright, it's just a paint job and a nice decal.
Omega Bracelet: Years of research in nanotechnology were required for this amazing product to reach this particular shade of purple. Beautiful...
Aerial Shoes: Originally designed to reach outer space, it's now being sold because its previous owner completely forgot about space suits...
Thunder Boots: If you've never seen a human reaching mach 2, here's your chance.
Glass of Sludge: Hideous taste, lots of bacteria, can block your oesophagus... But seriously, when you're THIS cool, you don't bother for details.
Basic Armor: When budget is a concern and you REALLY want some protection, try out the Basic Armour!
Crown of Magic: An amazingly powerful crown made from some sort of magical material, or something. Important and powerful mages are often seen wearing them.
Butcher's Set: This armour is taken from the remains of a Butcher, it would seem, though obviously it's not the same one that you faced in Diablo because this one looks exactly like a Great Unclean One!
