Ever wondered what skill counted as what element? This page has that info for you. Surrender to and Resist spells are effective against these skills. That would include armor sets for Bleed and Shock.
Example - Majestic set provides a 50% resistance to Shock. It reduces the damage from Stun Shot, a Shock attribute attack, by 50% and decreases the chance to be stunned by it by 50%
Example 2 - Resist Aqua 3 provides a 30% resistance to Water. Ice Dagger has 3 parts to it - the damage done immediately, the damage done over time, and the chance for the DoT to land. Resist Aqua reduces the chance for it to land and the damage done, but it does not reduce the damage over time.
Sleep and Hold skills are obvious (well, moreso than usual) so I'm not including them.
