3.5: advantage/disadvantage

[Asgurgolas]

I'm asking just because I haven't finished browsing the whole section yet (and because my programming ability sucks big time) but... is there an already-made extension out there to add the "advantage/disadvantage" effects from 5e to 3.5?

Thanks

Not that I'm aware of. Adding this in for all d20 rolls would be a bit of an undertaking.

Alright (one of my player plays a wizard who has learned the spell "Unluck", that basically would be "disadvantage on all 20 rolls"). While I never had real issues about that, it started to give me headaches when he began casting it on creatures able to do more than 3 attacks per round :s) XD

Thank you for the info :3
