Wow this is a crazy map. Shoutout to Collin255's UV route which uses both the archvile jumps which skips all 3 key cards.

The first jump is extremely difficult since there's only 4 archviles and I think you need at least 3 to target you to make the jump. HMP difficulty has an extra one so it may be worth playing on that difficulty just for that jump. You can actually make an arch vile jump where the pillar is lowered to save over 10 seconds, but I found it even more inconsistent.

I get the first jump very quickly but scuffed the second one a couple times.
