Vim's Boots of Protection
Acid, Cold, Fire, Darkrift, Poison, and Shock damage inflicted on the wearer is reduced by 2 points per damage type per attack/effect. Thus, if a single attack dealt a combination of at least two points each of Acid, Cold, Darkrift, Fire, Poison, AND Shock damage, these greaves would absorb 12 points of damage.
These greaves are a key ingredient for a multi-year transmute.
