Horticulous
"Horticulous Slimux is the Grand Cultivator of Nurgle, and possibly Nurgle’s first Daemon. While Horticulous is much beloved by his master, he is notorious among the usually jovial Daemons of Nurgle for his lack of humour, known as “old sour-seed” – although any Nurglings caught sharing this opinion tend to find themselves being used as bait for Mulch, his monstrous mount."
"Where Horticulous goes, a grotesque flourishing follows, as the soil swells with burgeoning flora that spread disease and decay like scents on a breeze. As he makes his progress across the battlefield, the terrain behind him is tilled to a rich loam from which Nurgle’s bounty may flourish."
"Remember this?"
"On the tabletop, Horticulous falls between a support character and a bulky heavy-hitter, and he works well when positioned at the centre of a Nurgle army."
"Horticulous’ most important ability is In Death There Is Life:"
Beast Handler
"Beast Handler is more specific, but no less deadly, and helps you get the most out of your Beasts of Nurgle."
"Re-rolls to charge add some flexibility to a fairly slow unit and combines well with Attention Seekers – by moving, running, and then taking a re-rollable charge, your Beasts of Nurgle could potentially cross a huge distance very quickly, allowing you to catch your opponent off guard. Similarly, re-rolling hit rolls of 1 means you’ll be able to deal more damage in close combat."
