I know that spell effects can be applied to cities and units. Can such effects be apllyed to other structures like watch towers and forts and dwellings. I was intrested in making some spells that would be benificial to players like me who like to fight against overwelming odds and need some defensive spells to help me and others turtle better against the spam. I usually fight like 5 emperor Level AI's.

I wanted to make a few more spells like this one that gave you more benifits for leaving units to guard choke points. I wanted to see if I could make the Garrison spell a castable on units themselves. That way I could garrison any structure like dwellings or the all important cave entrence or forts themselves. All the Garrison is, is a statistical buff for being in a certin place. I'd like to replecate that as ether an actual spell or building effect to promote a defensive play style.

You definitely can make a spell castable on units that reduces upkeep (AOW Unit Property: Upkeep modifier) and increases morale, for example (AOW Unit Property: Stat bonus). Reducing moving points could be very tricky. Removing them in Stat bonus will remove them in combat, too (they are the same on strategic map and in combat). But there is another strategic effect (Magic - Strategic Unit Effect : Reduce move points), which could work differently. But this needs testing. And it doesn't have a duration so it's probably instant one-time effect.
To make effect temporary you need to pack both above mentioned properties (upkeep and stat bonus) in AOW Unit property: Group, then put this property group in 'Magic- Strategic Unit Effect : temporary property'.
I don't see a possibility to cast this spell on structures so they give properties to units. Forts seem to be unable to give any properties. So the only thing you can do is to make this spell castable on units in your domain (and some properties could be made working in domain only). As forts generate domain, this could work. But this won't work with Watchtowers, for example.

Before doing all this, you definitely need to study a modding guide which was written by the devs. It's very useful and understandable (even though game systems are complex).
And I have to say that I paused playing this game for some time (modding, too) and these things are easy to forget. =)

That sounds like it still works for my needs. I could make a spell called "Hunker Down" that while in effect reduces movement speed or (distance) but adds a morale buff with a small upkeep discount. With this it could allow them more defensive proformance in forts aswell or pretty much anything. this wouuld stack with the already existing garrison buff and make for a nice defensive style spell for the hardy dwarves. Would be disadvantagous do use in the open field. But it would really work when u were defending walls with ranged units were movement isant as vital this would prevent it from being a spamable free stats spell as it adds a signifigant disadvatage to counter balance it.

Well, as I understand, you succeeded. Congrats! =)
Additionally you can make this spell castable in your domain only if you like.

Hey I was wondering, do you do Mod commissions?

What do you mean?

Well i'll be the first to admit i have no talent when it comes to modding. But i do love the game and I and my friends play it quite a bit. I was wondering if you'd do a mod for me on commission?

Well, I haven't been playing the game for about 1.5 years now and I don't do mods either. Besides, there are active modders which make mods of much larger scale and complexity. You probably should ask them, at the very least they will give you an advice, I think.

Ah alright. Thanks for your reply!
