Loop Hero

Don't go look up spoilers, as a large part of the game is the fun of discovery. Try different tiles near different things.

When you unlock the Encyclopedia, it'll tell you directly what mobs drop so there won't be ambiguity in that if you're worried about it.

I might just be an idiot but the wording was confusing to me, the Oblivion card removes a single tile or mob, not everything that you placed down since the game started.

Keep an eye on the deck selection card as you start new rounds, you will unlock new cards over time

The game hits a major progression wall pretty much right after the point where the demo ends, to the point where the speed of progressions slows down by 90% or so. It also starts to introduce some annoying mechanics, such as brigand mobs that can steal equipped items from you.

You can retreat while at the campfire and keep everything you found. If you press and hold the run away button in the bottom left, your dude will pause at the campfire the next time he goes through it. You can also turn on 'pause at the campfire' in the options menu.

Once you spawn the chapter boss, the Hero will still hit the camp before you engage the boss. This means that not only will camp-specific abilities trigger, but you can still retreat from the expedition with 100% of your haul without fighting the boss if you accidentally fill the boss gauge and don't feel confident you can win. Hold left-click on the retreat icon in the bottom right of the map window until the gears engage and it will trigger a retreat message when you hit the camp tile.

When the first map's boss spawns, he fill every empty tile around the campfire with a tile that buffs him. If those tiles are already have stuff in them, they're not replaced. So it's a good idea to fill up that area before the boss spawns.

Some bad tiles can spawn as a consequence of placing down other tiles (ex: the bandits who break your shit spawn a camp every 2 villages), so make sure you bring the card that can delete tiles.

The single most important thing to consider is what cards you bring. Cards that are good for one class are usually bad for another, and bringing cards that are detrimental or cards you don't actually need will make you weaker overall by either making the loop unnecessarily difficult or diluting your deck so the good cards come out less often.

Watchtowers are way stronger than you might expect and let you build a killbox around your campfire which really helps in the early stages of an expedition. Build all four and upgrade them to at least level 2 as soon as you can.
