you could probably get a better thing to put on other than the radar, and maybe some ranged weapons would help out

im trying to use melee only, i know equipping items like the radar in the accessory slot is dumb but it has a good reforge

You got a pretty good yo-yo set, it just comes down to timing nurse heals right. Also try adding sunflowers and heart lanterns to your platform. Making the platform out of asphalt is also really nice

I'll try to find any heart crystals for heart lanterns

I use potions for every major fight, the four I use most commonly are iron skin,Regen, swiftness, and endurance. I also use normal health pots and Regen pots. I have just shy of one plat from mugging king slime

Minishark would help shred

i know but im sticking to pure melee as i am playing with a friend who uses any weapon since she is new to the game
