Quick question,
I'm re-preparing for Skolas teaching to a couple of friends to see if I'm able to help people out here. As I posted earlier I got devastated on Round 4 (VIP), I just saw that Dead Orbit is selling an Arc shotgun, would it be worthwhile to buy it and give it an etheric light?
Also, I don't remember if you can put an atheric light to a weapon that does not have all the perks still active.
You can ascend any Legendary weapon or armor, regardless of upgrade status. With HoW, all weapons sold by vendors are re rollable so you can get a good roll and element in any of them.
The absolute best would be Found Verdict or 4th Horseman, but failing that there are a few standout options on sale. Judgment VI sold by New Monarchy is excellent; roll it for Arc and maybe Full Auto (very useful in PvE) and you have a winner. Party Crasher +1, which drops randomly from any Crucible playlist, is another good option. Felwinter's and Matador 64 are a tad too slow for my liking.
Having a Titan with the Helm of St. 14 isn't indispensable but it helps a ton. Otherwise, spec your bubble for Armor of Light instead of Blessing. You'll be attacked inside the bubble, but with Armor it's pretty hard to get killed. Camp the door with an Armor bubble and shotguns out, and you'll be fine! On the second round remember the VIP Target is actually the third captain to leave the door so you need to work fast at clearing those to be ready for the big guy.
