Ability Icons, Merc Huts, Air Boundry.

1.) Is it possible to remove unnessecary spell icons from heroes? My hero has 4 skills, a backpack and and attribute bonus. Which takes up the bottom row, while the backpack and attribute bonus take up the middle portion of the third lowest row... It works fine until I come under the effect of an ability "Like Shadowmeld being too close to a nightelf" Can I prevent this?

2.) Can you change the cooldown time and max # of units that you can purchase from Merc Camps?

3.) What do you find is the best way to keep flying units away from the boundry of your map?

1. You can make certain abilities not show their icon.

2. Edit the Merc Camp Shop. Delete units unwanted, and change cooldowns.

3. Use the "Pathing Blocker-Air" Doodads. Although I don't recommend using too many of them, that causes lag.
If it's spawns, then you should edit where you're sending them to.

1. You can hide passive abilities with the spellbook trick, check the Warcraft III Ability Guide for details on that.

2. The stock cooldown should be editable on the mercenary units themselves.

But what if I'm not using Merc units? In this paticular merc hut, it sells human, undead, nightelf and orc units. I want the merc camp to sell 2 of each of my units, without any cooldown down time, so once you purchase 2 you cannot purchase anymore of the same unit from that camp.

You can limit the training of units with triggers, look in the "player" trigger action category.

I think you can remove the shop-unit cooldown with making the replenish quantity to 9999999 and make starting quantiy to 2, or stock maximum (i dont know exactly it's name.) IF you are not sure what makes what, try it with some origingal melee-game items. Like healing pot,mana pot (checking requierements),...

I don't think this # can be set higher then 3600, unles you can change it somewhere in game constants.
