what you should be afraid of is not the Wall of Flesh, but Hardmode. you should have a full set of molten armor and the night's edge, + some other weapons( flamerang, phoenix blaster & a minishark). make a molten pickaxe to mine cobalt fast after beating WoF and get some weapons and armor quickly. Lastly, you must have full health and mana to withstand Hardmode enemies and craft / find some good magic weapons.
