If you want to master both bow and javelin, it is recommended to use Ice Arrow and Electric Gun in single player, which is the easiest way to pass

Bow: 20 Freezing Arrow, 20 Ice Arrow, 1 Freezing Arrow

Electricity: 20 Lightning Fury, and invest the remaining points into bonus skills

Passive: 1 each, and it is enough if the whole body equipment can be +5

I passed Hell with Ice Arrow at Expert level

It is easier to pass Hell in single player without a good bow or elemental attacks

I made a "harmony" after brushing the Countess of Hell until the 18# rune appeared

Good javelin is even harder to find unless you brush Mephisto or are lucky enough to get a Titan or Lightning Strike

It is recommended to use the Freezing Arrow mercenary weapon as the main one and use the rune word "Insight" to alleviate the embarrassing mana value

Switch to javelin when you encounter ice immunity and material immunity
