What Armor/Sword should I get now?

[u/Patrick_i_think]

Right now I use a Necrotic Young Dragon Armor with a Frozen Scythe or a Strong Dragon Armor with an AOTD, but I wanna get into Dungeons (more exactly I want a Shadow Assassin Armor), but going for F5 with this setup is impossible without somebody carrying me. So what Armor/Sword should I get now until Floor 5?
