I've been dropping 3 of Coins on everything, but the only chest I keep getting is that tarantula chest for hunters. I really want TG.

I got an exotic chest engram on my hunter a couple of days ago; I said "I really want that Twilight Garrison" so I moved it to my titan. Yesterday, I was at the tower with nico and Lawnmower, and remembered it was there - I told them I was really hoping that's what it would decrypt to (but I was assuming it would be yet another Crest of Alpha Lupi).

I got a Twilight Garrison.

Now it's just a matter of learning how to use it. ;)

It's super fun! especially when combined with a bit of Titan skating. I was using it in the daily heroic the other day to flank the shit out that cabal assault by zipping between the only two pieces of cover.

It takes some planning to use though, it's not a very reactive kind of thing like shadestep, having to jump and dodge means you end up using it a bit more offensively. It can also launch you into a fullspeed skate, whith is amazeballs.
