@ Bjorn: Hermes' Shoes perhaps?
You know, with tiny wings and stuff.

I'm still all towards Iron boots giving immunity to spike traps.
Just like protective shoes have metal-shod soles to save you
from stepping on nails.
@Thot: I'd love to see some "holy" damage or another - aimed
at dealing additional harm against the undead. There is a mention
of possibly having resistances/weaknesses against particular attack
types in the future (on the Lighthouse tracker thingy), I hope we
get to see this implemented at some point.
Anyway, I think what makes games like this a lot more fun is
the diversity of drops and multitude of unique items. With the
recent tweak in Artifacts' rarity, players won't be finding 90%
of the unique items in single run anymore, so that's a step in
the right direction, but it'd be really nice if the reprtoire was
bigger as well. Right now there's only a couple items for every
cathegory and say for the melee weapons - most of these
(actually all possible for non-Warriors) are guaranteed.
I really like how the player can now make choices beteen using
a Rathunter's Cloak for Poison immunity or a highly enchanted
cloak of regular kind for more stat points. Introduction of the
"can not be enchanted" flag on Artifacts was indeed a fine move
but it ruled out many of these uniques as viable choices. Say,
Golden Shield of Balance is poor when opposed to Dragonscale
Shield. So, instead of focusing on stats, let's go for uniqueness
via hard-to-get or completely distinct enchantments and bonuses.
Here's a couple examples:
- Dagger "Sunshine" [3/1/3/0] Lighsource, Burn
- Shortsword "the Restless Duelist" [4/5/-3/3] Disarm, Slow
- Leather Armor "Lifekeeper" [0/4/0/0] +5HPs, Magic resist
- Cloak of Shadows [0/1/0/2] Reduces the range at which monsters notice the player
- (Dwarver mining) Helmet of the explorer [0/3/-1/0] Lightsource, vastly increases trap detection chance
- Demonskin boots [0/4/0/0] Grant immunity to Lava damage
- Wand of Chaos - reinstitution of the old Wand of Chaos (random spell on use) but as an Artifact with infinite charges
etc.
