Poison is easier to figure it out, since it is logical that venom applied by wounding isn't the same as a toxic gas.
Psi abilities are confusing, because you have three different abilities, two of which bypass armor and shields and 3rd which doesn't (electrokinesis), but all are displayed as electrical damage in combat. If you haven't played a psi user, you won't know the difference. And the bilocation animation, which is a shadowy figure trying to melee you, isn't helping.
Why not simply rename the neural overload and bilocation damage to neural?
