Comments:  This is a built demo.

Saves 11 seconds off the previous max TAS. This could perhaps be 13s if all the pistol shots dealt 10-15 damage, I had enough trouble manipulating the Archvile to zap me from the correct positions with little delay so didn't pay much attention to that, so there are a few 5-damage shots. RNG doesn't advance at all while the Archvile is attacking so it would be difficult to fully optimise.
 
There's a bug where, with very precise positioning, the Archvile blast ends up in a different subsector to the player which can sometimes cause the line of sight calculations to fail for an unknown reason. It only happens with specific linedefs, perhaps due to precision errors from the oblique angles involved. That's how I take 20 damage from the zaps 4 times in a row. Each zap deals 70 damage to the Vile so it's necessary to maximise DPS in this map
