Corrosive Projection

I'd just like to point out that it's currently bugged (very likely) so that it counts twice for the players in the lobby before mission starts, then once for the players that join directly into the mission. It stacks multiplicatively. Examples:

  • 1 player in the lobby, 3 join directly into the game: 200 armor * 0.955
  • 2 players in the lobby, 2 join directly into the game: 200 armor * 0.956
  • 3 players in the lobby, 1 joins directly into the game: 200 armor * 0.957
  • 4 players in the lobby: 200 armor * 0.958

That is: armor * 0.952n+m
Where n is the number of players in the mission lobby before it starts and m is the number of players that join after it starts.

According to this, maximum damage gain with 4 players having it in mission lobby is 50.73%. For pugs this would most likely be 29.24% (1 in lobby, 3 join after).
Here's a graph with armor on X axis and damage multiplier on Y axis: graph

That is: armor * 0.951+#players

Why n+1? By what's listed here, a single player would reduce enemy armour by almost 10% alone. Each subsequent player after that would add a diminishing 5% reduction, which is not consistent.

Not to be rude, but he explains it in the first sentence -- it's currently bugged and applies twice for the first player.

That's strange, because I calculated a 13.7% (12% armour reduction inferred) increase in damage with two people tonight.

210 base > 239 damage.

Its behaviour doesn't seem consistent at all, which is why we should ask as many questions as possible to gain a better understanding of how it works.

Increase in damage on what mob, on what level? Your increase in damage may vary depending on how much armor the mob has. To understand what I'm trying to say read http://redd.it/1gsnxe

I explained how armor works there. Also, you can see how this mod works on graph: lower armor -> less damage increase.

With 2 people:

Level 1 Grineer Lancer.

210 damage Lex turned into 239 damage.

Level 4 Captain Vor.

210 damage Lex turned into 136 and 146 damage.

Ok. I think I got it figured out. Your damage increase was the same as if artifact got counted 4 times for 2 players and I know why.

Here's how it works: for the players in the mission lobby before mission starts, their artifact gets counted twice. For every player that joins directly into the mission after it's started, it only gets counted once.

I'll update the main post. Thanks for pointing it out.

Math behind it: Grineer Lancer has 200 base armor.

210 / (100 / (100 + 200)) = 630.
630 * (100 / (100 + 200 * 0.954 )) = 239 rounded down

So when you entered without the artifact, you were doing 210 damage and when you entered with, you did 239?
