Custom Trigger, Spell, and Ability Help

Sorry if this is in the wrong forum
I have 4 questions.
1) How do I create a spell for a unit that creates an building right in front of the unit?
2) How do I make an acolyte based custom unit move in increments of the same size of a blacksmith [pathing for the blacksmith, hunters hall, etc...]
3) How do I make 1 specific type of unit move by the arrow keys -> move right, <- move left,^ move up, and the down arrow key move down.

1. Use Feral Spirit as the Base spell, and change the unit to a building... that should do it.

2. What? I don't get it.

3. There have been quite a few posts about this. Search the forum, using the search bar... I'm pretty sure you'll find it.

Umm for question 2)
I want to make a unit steps equivalent to the size of a blacksmith.
E.G.
When a footman takes a step it moves 2 spaces/squares up, down, left, and right, instead of the footman walking by 1 square/spaces.
Sry for a very unclear questions, kind of hard to explain.
Also for question 1)
it works but is there way to make the buildings worth 1 food and not explode when casting another. I set the food cost for the building 1, and it works when summoning it, but doesnt work when casting it as an ability.

For question 1: Have a trigger replace wolves with buildings.

E: Unit enters Region
C: Region = Entire Map
Entering unit type = Feral spirit (or whatever)
A: Replace entering unit with 1 food farm.

That way, your farm won't actually count as the unit summoned by Feral Spirit, so it won't go away when you summon another one.

what about tiny castle/town hall ability ???

just make it a hero ability, or a unit, w/e u need, change the apropriate data and voila, u've got u'r self a building....oh, u need it in front of you...:)

what about this trigger
E:unit is summoned
C: summoned unit equals to wolf
a: replace it with a building :)

I'm not sure if it still applies to TFT, but in RoC, when a spell summons a structure, the game crashes. Try using the ability "Scout Tower" and those Great Halls and Town Halls item.
