The Advanced Shield is a top-tier defensive item you can get in 's later stages. It offers much better protection than earlier shields, but getting it requires a lot of time, effort, and resources.
This shield is way better at taking hits than the others and is worth all that comes with getting it. Having this shield can make the rest of the game a lot easier because once you have it on, you're going to be grateful every time it takes a hit for you.
You're going to need to explore different areas to craft the Advanced Shield. Make sure you're at a higher level before trying to get this armor becauseit will take a lot of time to do, but it also need to be unlocked first.
So, if you've just started the game or are not considering taking on the hardest bosses yet, you're probably not ready for this shield.
Instead, try to get more powerful weapons like crafting the Meowmere. To craft the Advanced Shield in, a top-tier shield with 1800 Shield Points and 21000 Durability, you need to put in a lot of effort, reach level 60, and have 5 Technology Points to unlock the crafting blueprint.
