Here's a few...
-Phial of Caladrial. Not as good as 1.1.1, but this is a ridiculously underrated item, IMHO.
-Shield of raw steel. Corruption and killing Guth scares a lot of people off, but if you want to clear the Tower with no problems, this item is tailor-made for it.
-Shezestriakis. The two-hit penalties are very minor in mid-to-late game. Otherwise basically the equivalent of wearing an extra tower shield.
-Black torc. As a missile, undead slayer + returns when thrown is very handy for PCs with decent Dx in the early-mid game. +10 speed and some useful early-game intrinsics makes this well worth it, especially for, say, mist elves who are really desperate for vortex protection.
-Bloody dagger. With a 50% crit rate, this thing punches well above its weight. It's probably one of the strongest non-artifact weapons in the game.
Hoping to win with every class, doomed. Archer, Barbarian, Bard, Beastfighter, Druid, Elementalist, Farmer, Fighter, Monk, and ULE Priest down.
