What element is this, how does it work?

I got a rough edge from a guild quest, with an element icon I haven't seen before.
It kinda looks a little skull with a fuse on it.
I'm assuming it's blast. Like blast coating since, when I tested it out, it did indeed blow up in monster's faces (And misc body parts), occasionally. And occasionally it leaves a little fire effect, or a little red smoke cloud... What I using here?

It's Blast. I'm pretty sure you need Awaken on Rough Edge for it to activate, though.

Still seems to make em blow up, eventually, even in axe mode.

Pretty sure Guild Quest weapons can have different elements. I'm pretty sure Rough Edge had a Dragon Phial. What you probably have is a relic version that happened to spawn with Blast damage.

Mechanically, Blast works identically to a status weapon, except instead of triggering a status effect that lasts X time, it's instant and deals damage outright. Plenty of monsters have a pretty low resistance to Blast early on, but it'll ramp up as you start 'sploding them.

Specifically, Blast works by building up on a monster on random attacks (hence the little fiery clouds), and when it reaches the resistance threshold and triggers, BOOM: Flat damage on whatever part you triggered the explosion on. The monster's resistance to blast goes up a bit, and the build-up resets. It's a really good part-breaker and damage-dealer, and a good substitute for elements you don't have or when you're fighting multiple monsters without a common elemental or even status weakness.

Yup, when i dont want to go pure RAW I like to go with blast weapons. They ussually have a high enough raw that the blast is just a nice effect. They are pretty good general weapons as instacake pointed out.
