Reavers use one-handed melee weapons, and...well, that's about it.
Hel-Reavers put forward a fair fight, although ultimately, they are standard humanoid enemies with a low amount of total health. The usual rule applies. When they're in melee range, block or parry their attacks and dish out punishment when they're open. They have a low stun threshold, so barehanded blows are an effective angle.
One specific attack to watch out for is a very quick thrust with their melee weapon. This move comes out fast, and so it can be hard to block in time. Our advice is to keep your shield raised when you get within range of their weapon, just in case. Once blocked, you can go straight into your own strikes.
