If you've been to mountains, how about wolf jerky instead of boar jerky? Also, honey is a sta food; you will find lots of cloudberries in the plains, which are better and cheap to eat. Keep a stack of heal and stamina potions on you, in your hotbar, just in case. Have bonemass defensive ability too.

Be quiet, keep your head on a swivel, especially looking out for the squitos. Range 'em down before they see you if you can. Collect their stingers and make very good arrows from them. You can easily kill a squito with a cheap wood arrow, but I use needle arrows on everything else in plains. I always keep a couple hundred on me. Circle around tar pits from a distance or avoid them altogether. Look for bones and listen for the oozy sounds for evidence of a tar pit.

I built a flax farming operation in the plains too, necessary for the padded armor. I built it starting from a fuling tower. It doesn't grow in meadows, so you will have some plains construction to do. I built mine from stone; seemed like the damage from critters in the plains would demolish wood.

I don't like staying out in plains at night. I explore during the day, and retreat to safer places at night. Explore from safer staging camps if you can.

I think I'd recommend hitting the mountains first. Get silver. I'd absolutely want silver weapons and a silver shield. Silver armor is optional. You'll also want mountain food - onions and wolf meat make some really excellent and not particularly expensive food options (wolf skewer, wolf jerky - wolf jerky in particular is dirt cheap and adequately good). You can keep using sausages but honey and boar jerky aren't even remotely good enough.

UPDATE: I greatly appreciate everyones input.

So i switched out my iron chest for Root. I sailed off from one portal to a landmass next to it. Turns out its consists of mostly plains with some swamp at the top, hilariously, the very bottom tip is black forest so i dropped a portal there.

Portaled back home to restock then back to the new plains one. Immediately, i'm attacked by 2 fulings one of them being a 1 star. Thankfully, both were just wielding knives so they were easy kills. Got stung by a deathsquito in RIGHT after i dropped the duo and as amazed at the lack of damage done.

Found a few lox, unfortunately before i could establish an appropriate spot, a stupid ass deer caught one's attention and led it DIRECTLY to my portal. The lone lox double teamed me with a deathsquito and damn near killed me dropping my health to just 40. Survived, killed em both then sniped the other unsuspecting lox out of rage.

Forgot to mention, right before i collected the last of the lox loot, YOU ARE BEING HUNTED. Awesome(sarcasm)! Screw it, i'll kill em all.......which i did. Full load of loot headed home. dozen lox meat over a dozen wolf meat.

I know for a fact there is at least one fuling camp on this landmass so that will be my next target. Plan on sniping them from afar, depending on the terrain. Again, thank for the help fellas.

Make friends with the lox. All the lox. Don't try to build enclosures for them, that way madness lies.

my advice; bows kill them before they aggro

This.

Root chest makes it less of a hassle in dealing with sneaky deathsquitos or the javelin fulings. Great trade off in being weaker against shamans or torch fulings where 1 is easier to range down and the other easier to avoid.

Boar meat and honey is subpar in going into plains imo. Turnip stew and minced stew which uses boar meat would be a bit better.

Turn around. Tar is the dumbest thing they have done to this game yet, and believe me that's saying a lot.

If you suck at parrying, use heavier shield and a sword (they're faster than maces or axes) to either slap Deathsquitos before they sting you or stagger them with block and slap them while they're dazed.

You can't outrun them, you just have to kill them before they kill you. Best is sniping them before they notice you.

I Would go with the silver armor all uppgraded anytime and have Bonemass power ready if needed and also have potion poison resistance with me.
I also wish you would not haved asked about this things at all sins all the suprise and excitment going in to a new biome not knowing anything is what gives you the best game memories and experience.

The deathsquitos scare me off from even scouting the plains in a boat.

Practice parrying and try to eat 2 HP food 1 stamina food

you need better food than that, turnip/onion soup for stamina boost, wolf jerky, sausage for helth. and stay away from tar pits unless you know how to deal with it. i find that roots torso armor is better in plain (piercing resistance) to deal with getting cheapshot by that pesky mosqouitos. and bonemass buff for panic mode.

Use root chest piece and your immune to deathsquito and fuling with spear, just be careful about fire damage

Deathsquitos are handled depending on whether or not you can't take a hit while blocking with a shield. If you can, block then swing. Otherwise just time your swing to hit it before it hits you and hope for the best.

The Tar Pits are annoying because the growths hit you with this tar crap which slows you down incredibly. Best handled at range with a bow.

Fuling Camps.... lots of bow use from the periphery until you whittle them down to nothing. Takes a while.

Generally the bow is a great way to handle most things in the plains which haven't already aggroed on you.

I would skip wolf armor to add more difficulty, but better food is a must. Try raiding smaller village for flax and barley so you can make padded armor and better foods as soon as possible. If you have tamed wolves use them as tanks. But please focus on food. The food you use is too weak for plains.
And consider making a lot of poison bombs. They work pretty good against groups of fulings and wolves too if you get “you are being hunted event”.
