I'm not sure what the numbers should be...
Venom Sword - +2 base damage, Poison: 3
Balanced Sword - +2 base damage, +2XP for same-level kill
Blue Plate - +1 mana/kill, 1 damage reduction/lvl
Alternative: Blue Neclace - After killing an enemy, your next glyph cast costs 2 mana less.
Perseverance Trophy - +25% damage
Goblet Of Health - 40% health restored, 2x regen for next 5 tiles.
(Similarly for Chalice of Mana)
Coppertone Urn - Cleanses burn/corrosion AND grants 5 stacks of prevention (consumed by either status proc)
(Similarly for Egg Yolk Breakfast)
Pwnzor's Keg of Xtreme Hurt - 1x Might stack, auto-replenish after the next 4 attacks. Next attack drops monster health by 25%.
Overzealous Helm - Protection from Poison, Mana burn, and Curse
Guardian's Necklace - 8 beads' worth of enchantment in ONE large item slot! What an awesome deal!
Witchalok Mantle - Grants Might and a layer of Stoneskin for each fireball cast.
