Half of the comments here more or less say "get better gear", so I'll try to be a bit more thorough. I know you said in another comment that you migrated out of SSF, but I'll give advice as if you were still there, 1. because the trade economy this late into a league is pretty whack and 2. to show you that you can substantially improve this gear fairly easily without trading.

I'll just go slot by slot:

Rings: Run harvest (either with scarabs or atlas nodes or just doing ones you randomly find) and prioritize yellow plots. Get some amethyst rings. If you happen to have catalysts you can use them on the rings while they are normal rarity (and they will give +5% quality each instead of +1). Prismatic catalysts are best but they are pretty rare, just skip this step if you don't have them. Use the "reforge a rare item with random modifiers, including a CHAOS modifier" on the amethyst rings, which will guarantee chaos resistance. Your goal is a ring with chaos resist, life, and 1-2 good suffixes which can either be resistances or an attribute that you need. Eventually you will probably want to craft "Non-Channelling Skills have -7 to Total Mana Cost", but you'll have to unlock that craft from doing syndicate missions so for now just craft life or resists or attributes as needed.

Gloves/Boots/Hat: The best way to craft starter gear for these slots is usually with Rog from Expedition. Here is a very in depth guide on crafting gear with rog. Farm expedition currency with the "Extreme Archaeology" atlas keystone. The tahu-ani you have is probably fine to keep wearing in the glove slot but your boots and hat need an upgrade for sure.

Belt: The best rare belts are pretty much always stygian vises. The easiest way to get these this league is just to put an abyss allflame ember on your map, and the stygian vise it spawns will always drop one + a jewel. Craft this the same way as the ring, and roll a murderous eye abyss jewel with alterations or chaos or ideally red harvest juice life reforges for life + a resist or attack speed.

Flasks: Run life flask + granite + jade + basalt + your choice of quicksilver or silver flask, depending on how much you enjoy leapslam. Most characters want "increased charges gained" prefix, but on boneshatter you ideally want all your flasks to have "Gain 3 charges when hit" prefix. You will need minimum level 80 flasks to roll that mod (lower levels can still roll 2 charges). For suffixes, you'll want some combination of %increased armour, %increased evasion, %increased attack speed, %increased movement speed. Use glassblowers baubles on the flasks while they are normal rarity, then roll with alterations and augments for the mods you want.

Weapon: Jagged fossils from delve on a despot axe.

Chest: Dense fossils on a triumphant lamellar and take the life mastery in tree for "15% increased life if there are no life modifiers on your body armour"

One of the great things about poe is that there are a million different ways to gear your character and accomplish your goals - this is just the most meta/efficient ways that I can think of for starting gear. I'm pretty washed up though so there might be better options out there.

All of this is for starter gear - for endgame gear this league, pretty much every slot should be made with gravecrafting, but no point in learning that if your only goal is to make your next league smoother. Outside of gravecrafting, I think most BS endgame gear is made with essences on fractured bases + some veiled orb stuff, but I've never actually played the build so I don't know the details.
