What the source confirms
The official experience thumbnail visibly names Axe and labels it Epic. That makes the identity and rarity safe to publish.
Role hypothesis to test
Use as a candidate when your loadout lacks close crowd control.
What remains unknown
Range and attack pattern are not quantified in public official assets.
Run a controlled comparison: keep the rest of your loadout stable, change this slot, and record what ends the run. That result is more useful than a copied tier label with no patch or source.
