650+ hrs in, tips for swamps:

The dif level from BF to Swamp is high. So is Mountains to Plains. Don't go into the swamps at night until you have better equipment. Wraiths will tear u up. Watch the fire imps, they can be deadly at lower equip levels. Get that bronze armor on at least your chest upgraded and a shield helps tons (round for stagger blocking).

First is poison resist potions. Very needed early on. Health potions are always useful, so are stamina potions. FOOD IS THE KEY other than poison potions. You need to get to sausages to feel comfortable exploring. Get those entrails and make em. If you have the vendor found and enough cash (350 coins + extra) you can get the fishing rod. One fish, one boar meat, and one sausage puts you at good HPs...

Oozes and blobs: Oozes kill with a bow asap, they will break into smaller units. If you wait until the blob jumps and lands near you, you can get a shot or 2 off before they poison and kill them, IF you have iron weapons. Until then hit and run or use bows on them.

Drugar: REMEMBER at first they are a weapon class above you. They have iron and you have bronze coming in. Kill archers first or take cover behind trees to lure them in closer to attack. Watch spawners, they can overrun you if an elite spawns. Usually you can stand still and as they ramp to swing, just take one step back and they miss, you counter. Or stagger block and counter. Get entrails!

Wraiths: Mostly at night, mostly... sometimes in huts. Block or run at low levels. They can hit hard and fly, especially a 1 or 2 star.

Fire Imps: Will avoid water, but have good range and can burn you fast early on. Avoid, or hold bow shot until they are just about to shoot at you, then shoot and move and you will kill them easy (low HP) and should avoid the fireball incoming.

Leeches: Avoid, use Hoe to raise ground, shoot with arrows, or use Abyssal Harpoon to drag out of water. Honestly, if you watch your footing they shouldn't be an issue. They DO poison, so careful if you fall in deeper water.

Skeletons: Destroy with extreme prejudice. Just watch the archers, kill first.

Remember, most units can't climb, so big tree branches will help, just watch the blobs they CAN jump.

BLUNT WEAPONS ARE KEY. They are the least resisted dmg type and a good mace will get you far in the swamps. Collect gunk from trees (big green blobs on some trees) for the bow you will make later on in the game.

It's best to bring your swamp key, health around 100, a few poison potions and fire arrows + blunt weapon in at the start. Then work to a crypt and go in and get some iron. Then upgrade mace and armor until it hurts. GET AS MUCH IRON AS YOU CAN. Eventually, the padded armor later in the game needs iron, it helps to have leftovers..

In crypts: Keep to the right wall when you enter and follow it wherever it goes. Eventually, you will end up back at the start and not get lost. Bring more than one pickaxe, you will be digging for iron a ton. Put iron you find in a chest in the crypt in a cleared room near the entrance until you clear the place out. Weight will kill you if you don't watch.

Crypt rooms: Try to dig out the tops and leave most of the bottom there or cut a hole down the middle. This way the creatures can't get through at you and you can pick them off before charging in an area. Opened / cleared crypts are safe to stay in if you get caught out at night just like tombs in BF.

Really the only way to conquer a biome is to be in it. Just move slow, take your time, watch the water and get that iron.

Fortune favors the Brave!
