hey dude when you said
First of all, there is no contest to build the most powerful character ever using DFRPG rules.
Secondly, supernatural heavyweights are plain beyond stats, at least using the existing rules. Mab can cause a snowstorm big enough to cover the entire city of Chicago and barely exert herself. Uriel killed the firstborn children of an entire nation. The Morningstar created a circle of Hellfire a quarter-mile across hot enough to instantly obliterate Denarians and powerful enough to cut off the Archive (a lesser supernatural heavyweight herself) without even being present on the same world at all. Any one of those feats would require thousands of shifts of power, not dozens or hundreds. A supernatural heavyweight that is uncontrolled and unbound by rules could well destroy civilization - which is why breaking the balance of Faerie back in Summer Knight was a really bad idea. It is also why summoning Old Ones is a bad idea.
Third, the absolute maximum base power the system allows in evocation if you follow the rules is 24 power. That's nowhere near thousands. So if you follow the rules, you plain can't stat them.
first no they aren't above stats to the existing rules or all of them at least.
second Averax could kill mab for 3 reasons
1 mab has a weakness averax has unknown catches to his immunity and no catches for his legendary Toughness, stoicism, status.
2 mab can control cold weather on her but averax could just ripe a whole in reality sucking her into the outer gate were she couldn't do F#@king Sh@t.
3 sure averax could do that but what your thinking right now before you read this next sentence is that well he still has to beat mabs skills to do this well mab a has most of her skills at +8 some at +9, +10. all of averax's stats are at +15 in human form/guise. so she would have to get great positives and he would have to get negatives for her to win
lastly it would not take 1000's of refresh to do the ring of hellfire or the chicago covering snow storm, yes those are impressive but for every power shift you have to remember that it doubles in size so it would probably take a couple hundred but couple thousand would be more like the next ice age.
P.S you contradicted yourself bravo my friend bravo. by saying supernatural heavyweights do go by the rules then at the end you state by the rules evocation only goes up to 24 power.
if you can bring a better comeback than that i will congratulate you.
