Taking a break from deep forest ruins and a shaky cam of an upcoming fighter, ARMS has seen fit to reveal the addition of a new attribute. These kinds of special, charged effects have been attached to nearly every ARMS type, though with the few added since launch, none have brought new ones.

The video in the above tweet shows a new, pinkish skull icon joining the existing attributes. No confirmation on what it’ll be, but my guesses are either a health sapping Poison or some sort of Curse. Both somewhat play into the peeks at the new character we’ve received, as this lead-up to the next patch continues.
