And to think that they said I couldn't oneshot an Archvillain...
On the test server during the testing for Inventions, there were a number of interesting bugs. The 'Touch of Lady Grey' proc (chance for Negative damage) originally
was negative damage -- when it went off, it would do a negative amount of damage, healing your target. They fixed that, but broke it differently; when it went off, it would do some absurdly huge multiple of your target's undamaged hit points. Just for giggles, I took the character I'd slotted with the proc out to Crey's Folly, and I
did one-shot Jurassik, doing (if I'm remembering the number correctly -- I've got a screenshot at home) '6.0442e+11' points of damage to him when the proc went off on my first attack. Some people were able to get marginally higher damage, but at the time it was amusing to note that the CoH engine was capable of transitioning smoothly into scientific notation when numbers got too big.
I may not be able to turn up
all of my boxes; I'm pretty sure I still have the box for CoV ready to hand, with the HeroClix figures still in it. I also made a point of screenshotting my NCSoft City of Heroes account page showing all of the game codes that I applied to my account over the years.
