Longer Spell Durations/Custom Spells

[Khaennn]

I'm trying to make Blood Elf Illusion longer than 5 minutes, so I don't have to keep refreshing it.. Is this possible with HeidiSQL? I mean, I've searched everywhere. If I can't do this, is it possible to create my own spell with this same effect, but for a longer duration?

No, sorry.

Spells are handled in the dbc files and database both, they are also handled both client side and server side, you could possibly do this but you couldn't accomplish it without a custom patch. If this were possible look into the model editing section and take a look in the Spells.dbc file.

Search for DBC edits and custom patching, maybe even spell swap could provide useful info.
