Yeah, took a break and saw Telmo get 120 dung
Here's the only pic I managed to get. Some nerd kept standing on him
It actually doesn't look like a skillcape.. more like a pimp ardy cloak. And also it has black particles when you move, which is a nice touch
The emote is a little tricky to describe since I only saw him use it a few times. It's not an alternation between 3 emotes like lesser dung cape, but rather all 3 mixed into one. All 3 forms of melee, mage and range feature you slaying a specific dungeoneering boss. I wasn't able to make out too many.. but the mage uses fire surge and melee kills what in my opinion looks like nightgazer by stabbing it in its eye, making black "blood" particles flow out. I wish I could give you more info but some nerd wouldn't stop standing on him.
