A Simple Bonus Spell

[Silvenon]

Lol, I haven't been spell making for a while now...what is the best way to add bonuses (for example to increase armor) for..lets say 30 seconds? Can it be done without periodically checking if the unit has the buff? I also have to keep an eye for a possibility of dispel, right?

I'm only interested in the construction of this code, I know how to add bonuses

The best would be the spell in the object editor

I forgot mention, I mean with triggers.
