Notably Aragorn has enhanced senses that actually make it nigh-impossible to be caught off guard by a conventional trick like that.
"In addition the people, tall and strong, were agile, andextremely “aware”: that is they were in control of their bodily actions, andof any tool or material they handled, and seldom made absent-minded orblundering movements; and they were very difficult to take “off theirguard”."
Anyway, for a brief run down, Aragorn is above skill for all mortal warriors of the Third-Age. This includes other one-man armies like Boromir (who did die when fighting over a hundred Uruks, but notably without his shield and he was only wounded by arrow fire and by the time he's dead his sword is broken), Gimli who jumped into the breach at Helm's Deep and survived solo for a while without any major injuries, Eomer and Imrahil who also came out of the Battle of Pelennor Fields without any injuries, etc.
So like DaReaperMan said, both are one man armies, with Varian having the better showings but it's close enough (plus Aragorn has senses that specifically help with this kind of skill based fight).
Aragorn however doesn't have much going for equipment. Notably, if this is Aragorn as "Strider" he is in light armour, however, Two Towers and onwards he's in the best Rohirric and later Gondorian steel armour (with helmet too) so he's not unarmoured tbf. It just wasn't worth listing on profile. That aside, he still has the Elessar to passively augment his "Low" Regeneration which is more of a stamina buff let's be real than actually pragmatic healing. He also still has his scabbard that renders the weapon drawn from it invulnerable, so he has an advantage there. The Elendilmir is inconsistent as help at best and useless here.
Now, there are other things to consider than that.
- Mind Manip resistance for Varian is notably listed as only against Mind Control. If this is true, then Aragorn can read his thoughts mid-combat for advantages (which helps nullify the surprise of Varian's unconventionality in weapon amount more)
- Theoretically, Aragorn could curse his weapon so that Varian insta-dies from picking it up or touching it. But that's massively OOC.
- Two swords do give Aragorn a flat-out disadvantage no matter what. 2 is more than 1 and with his better LS Varian can keep Aragorn's blade locked in place if he gets him in a bad angle. On the flip side better AP for Aragorn interacts weirdly here since I'm unsure if AP or LS matters more for parrying or disarming so I'll leave that unmentioned.
All in all... uh...
Idk? Tbh Aragorn is lower in skill overall but he can compensate for that but Varian has a flat out advantage in two blades. But Aragorn also has a flat out advantage in AP and seems to have Telepathy to let him read Varian's mind...
I'm going to be a coward and just say Incon until I get the Mind Manip resistance clarified.
