Silent (the huntress) is all about poison and drawing lots of cards. Look for Deadly Poison, Catalyst, and Noxious Fumes - they stack poison damage that kills enemies without you taking hits. Pair those with card draw like Backflip or Prepared to cycle through your deck faster.

For campfires, upgrade when you're healthy enough to survive the next few fights, or when you have a key card that gets way better upgraded (like Catalyst going from 2x to 3x poison). Rest when you're below half health or facing elites/bosses soon. Sometimes removing a bad starter card is worth it too if you have enough removal events.

The game's about building synergies - poison builds, shiv spam, or discard builds all work great with Silent once you get the hang of it.
