Can you cheat at D&D?

[Divide by Zero]

You'd love my Spell Resistance house rules then. I don't go for the boring ''your spell fades away''. I got a list of random things.....and #3 is Spell Reflection: the spell bounces off the target at a random angle and effects everything that is a legitimate target. So cast a lightning bolt at the demon, fail your SR check, and one of a dozen options is that you might hit a member of your group with your own spell! More random fun!

What I'm reading here is "Don't play a caster in jedipotter's games."
