I am not an expert, but if you combine Cloak of Resonance (new core) with Agnes Baker (old core), you get a pretty powerful combo:

1) Agnes takes an horror --> ennemy takes a damage

2) Move horror onto cloak of resonance using lucky charm --> ennemy takes another damage

On the next turn, you can even place this horror back to Agnes etc. which basically gives you a free damage each turn.

If you play with an investigator which has low sanity, you can even heal your ally... It seems very handy to me.

This card is very good with Agatha signature Ocula Obscura. You basically get 1 free charge spell and 1 guarantee 3 damages once per tern(Might be more, if you can find a way to ready Ocula Obscura). However you need to fish for 0 token first, which is not difficult if you run Breath of the Sleeper or Eyes of the Dreamer.

Ravenous Myconid came out with it's bonded event card Uncanny Growth which comes with a bolded Investigate action on it to power up the myconid. You are able to return Uncanny Growth to back to your hand every turn using Ravenous Myconid's fast ability (Like how Dream Diary works). This effectively gives you a guaranteed free investigate action each turn when you use Uncanny Growth with Farsight. On top of that, you power up the Myconid more each time that you do it. It's a near perfect synergy, close to broken though.

I have only played this card in ONE deck. and that deck was shotgun Harrigan where it performed pretty well actually.

I was all in on shotgun, which late in the campaign included a custom modification, custom ammunition and an enchant weapon.

So I was frequently dolling out 5-8 damage on basically any attack, making relentless actually kinda good as every enemy slain was being massively overkilled, I once discarded relentless for about 20-something resources.....

In most other decks this card is bad. Most decks are not built around over-killing enemies becuase well.... Overkilling usually means you spent more effort than it was worth to kill something, in which case getting compensated 1 resource per damage is not a great rate.

Would love it if they made an XP version of this card though.

When you couldn't shoot enemies in your face with this card(before the taboo) this card had absoloutely 0 homes as a card. If you're a guardian character that's running two-armed guns AND are willing to spend xp on an upgrade for one, you're probably your group's main damage dealer so not being able to fight things in your face was a death sentance for this card.

Now it is instead a hyper-niche card that has a few decks that maybe want it.

I played it in a campaign where I played Mark Harrigan. I hadn't really gone all in on the OG shotgun before so I decided to REALLY go all in on it in forgotten age with Custom Modification from scarlet keys, Custom Ammunition, Enchant weapon, the works. and down the line since this card had got the taboo I went for this card in the mix as well.

I would not call Telescopic sight a good card, but I will grant you that it is the type of card you feel like a super-genius when you make it work because when it does it's thing it's kind of a flex

I used it on a serpent of Yoth that was engaged with another investigator at a connecting location and did an attack that did a total of 7 damage (shotgun+custom modification+Custom ammunition) reduced by 1 to still overkill it enough to put a damage on relentless.

So overall this card is cool, but only actually useful in about 0.0002% of decks.
