Spells/Arts + all their crap

[John Adams]

Here's a general question. When you cast a DD spell in game, you get for instance a bolt of lightning, you get the ground shaking, you get a sound effect, and sometimes, other stuff.
How will all this be handled? Do we have to code these effects into the spells LUA? Or will the server somehow know when to shake the ground, create thunder, or make some other visual/audible effect?
