Bastion Chain (Patreon)

Armor (chain mail), rare (requires attunement)

The chains of this armor shift naturally with your movements. You gain a +1 bonus to AC while you wear this armor, which doesn't impose disadvantage on Dexterity (Stealth) checks you make. In addition, the chains flow around you reflexively when you're surrounded; the armor's bonus to AC increases to +2 when three or more hostile creatures are within 5 feet of you.

The fighter gazed, unfazed, at the overwhelming forces charging the front gate. He felt the chains that hung from him twist and react in anticipation.

He glanced back at his fellow soldiers and said one thing before charging into battle...

"Let them come"
