How many extra gems do you use?

[tinkthank]

My first poll attempt, excuse me if rotten.

The question in the title refers to extra gems when casting rituals and dispelling same.

Obviously, the only answer is "it depends". Right. Depends on your race, on your gem situation, on your enemies, on the type of spell being cast (burden of time oh please make it go away vs mother oak not bothering me so acutely)
Of course. I am just trying to get a gggeeennneeerraaalll feel.

So I will try to contextualize with a few questions. Of course, I cant possible cover all situations, but bear with me if possible and feel free to elucidate your answers by giving your thoughts in your Posts.
