When you start the game by logging in and spending all 120 Original Resin, you will finish with six completed Ley Line deposits, 20 Original Resin each, and 600 adventure rank experience points. Each fight on Ley Line Deposit takes only a few minutes and grants a hundred adventure rank experience points.

Mora is better since almost everything in the game requires money. There are two types of deposits one provides Mora, and the other one provides experience books to train your character levels.

The best way to spend all of your Original Resin would be by opening Ley Line deposits when early in the game. It is recommended to never keep your Original Resin at max 120 cap because you're losing out on your valuable adventure rank experience.

It is required for completing domains, fighting world bosses, and opening Ley Line deposits. Original Resin in Genshin Impact is the energy system of the game.
