Ward is a suffix that turns up on Off Hand and Relic. It gives Ward: +24 to +40 at its lowest step, +688 to +944 at its best — and you need item level 116 before the best one can appear at all.

It comes up at weight 5 when the game rolls affixes, never doubles up with another affix that does the same job (ward), and it is what puts the Veil, the Shroud, the Mantle, the Bastion and Invulnerability in an item's name — so you might pick up a Wand of the Veil.

16 Uniques lock it to a fixed number: The Unopened Door, The Wyrm's Eyelid, The Unmoved Wall, The Wall's Weight, The Glassblower's Breath and The Glacier's Patience and 10 more.
