Which actions increase loyalty of skaven?

[Kyso4ek]

I ve just lost an immortal lord to loyalty.
Is there a list of events that will help you keep your heroes loyal?

[Inardesco]

Basically the killing of others, raiding, anything that isnt consisting of sitting around aimlessly, winning battles

[RCMidas]

Also keep your Legendary Lord at a higher level than everyone else. Loyalty drops faster if a Lord is of a higher level to your Legendary Lord - Malekith has an extra debuff to make it drop even faster for his overleveled Lords.

[Vanhorstmann]

From the wiki:
-Winning a battle with a lord can increase that lord's loyalty.
-Raiding with an army.
-Recruiting units into a lord's army.
-Equipping items, banners and followers to a lord can increase their loyalty.
-Har Ganeth has a faction mechanic which can cause lord to gain loyalty at the start of your turn, when Hellebron is still fairly young.
-The Thirteenth Scheme rite for Skaven gives Lords a chance to gain +2 loyalty each turn while it is active.
-Vampire Coast Lords have traits that say specifically what will increase their loyalty. For example, a firestarter gains loyalty through sacking or razing settlements.

And don't disband too many units from their army
