Hi, I play vs. the AI, and I'm fast concluding that the single most useful Sin is the ritual that lets me fortify my own walls. Not because I want the walls fortified, not at all. That seems generally pointless. Most of the time, if the AI is tunnelling through the walls in my treasury, I've probably already lost. That's not why I value the fortify ritual. It's because I want my workers doing something useful. The number of times I see a battle with KO'd critters from both sides, none of my imps collecting them, and find most of my workers are fortifying nearby walls is crazy ... and it just makes me want to cry in frustration. I'm reaching the point that I don't launch an attack until I've cast fortify to stop my imps getting distracted on irrelevant tasks. Can the imp-AI be set so that they'll value (almost?) everything else over fortifying? If there are KO'd mobs, dead mobs, flagged-dirt, empty tavern meat cannons - anything - that they can do, I want them doing it rather than fortifying walls. I'd be happy with the outcome that they only fortify if either of these applies: a. I've dropped an imp beside a wall, and there's nothing else for them to do within a ?4? tile radius, or b. there's literally nothing else to do anywhere. Something else that might help is flagging these imps (ones who are fortifying) as 'idle' so I know I can grab them for re-use. Cheers, Julian.
