So I've been away from the game for about a couple years but have some time to run for a little while. I just watched the WR for UVHM Geared Sal and I realized that so much has changed and I just had a few questions on the way these unfamiliar strats worked.

1. How does the swordsplosion on the beacon thing work? (like I know that de-equiping it can make it hurt friendly targets but like how would I use this stat to skip beacon)? 2.Why all the extra save quits during End of The Line?
2. Which extra missions need to be picked up and when do you trigger their dialogue to skip other dialogue?
