I'm pretty sure theres already a electrocuting suggestion that has been marked looking into, As far as nausea goes I don't think its in the best interest of others.
Many actually get sick from having the nausea effect on in minecraft, Which would mean one would be feeling sick for the rest of the battle which wouldn't be fair in my opinion. Aswell as nausea effect hurting some's eyes to the point of them needing to take a break from minecraft for 10-20 minutes to feel okay again.
All nonsense aside, I do not think it'd be a great addition to projectkorra.
