Actually, I didn’t even get a t-shirt, what a scam. All that happened after depleting it’s HP is that the name plate no longer appears when you mouse over it.
I was doing damage and build tests, and after a while noticed I was doing a whole lot less damage. I thought there was a bug or something, and realised that the dummy was actually below 75%, so I was no longer getting the cold presence buff on Shatter Strike. It didn’t even occur to me that I could actually hurt it.
It took me about 30 minutes, and I was hoping there’d be a pot of gold at the end of rainbow. Was it worth it? Probably not.
Would be hilarious if it dropped a Bokken. Could be really cool if it was a good item. Really low damage, but high attack speed and several ailments it applies.
