just some questions

how do i make it such that a unit will gain another ability when casting one or attacking another units? (e.g. gain cleaving attack when starts an ability)(e.g. gain critical strike when attacking a unit with specific buff) also, the icons wont be shown.

secondly, how do i set the timed life of buffs(summoned unit/normal buff)? (e.g. Skeleton Warrior summoned lasts (5 + Int x 0.4) seconds) (e.g. Roar buff lasts (Int x 0.15) seconds)

To make a unit gain an ability when casting one or attacking is simple, use the GUI actions:
-Unit - Add ability and Unit - Remove ability or Player - Enable/Disable Ability.
But, I think that u are having problem to make the icons don't show, I really don't know how to do it!

Well, to modify the duration of a buff per trigger, I think that have not how to do it, but, I have another way that may be what you are looking for:
Create a trigger for when a unit casts an ability, and then, wait (5+ int x0.4) and remove the buff from the unit.

Use Spell Book ability. To do this create custom ability based on spell book, add that Critical Strike to that spell book.

Now to activate/deactivate the ability, you just add/remove that spell book ability.

so i just remove the icon of the spellbook ability?

Yup, and don't forget to disable he spell book.

sorry, but what do you mean by disable?

Hmm, I never thought in this way !
But, leopard, you are saying to remove the Spell Book Ability or the Critical Strike of the spell book?
