The order gamestratwiki recommends
gamestratwiki lays out a specific early-game sequence: redeem every available code, fight enemies until your HP rises, return to the Reaper to bring it back down, and repeat that revive cycle continuously. That loop is the foundation everything else in your first session builds on.
Redeem codes before you do anything else
Check the /codes page before your first death-revive loop. Active codes hand out Death Coins and Soul Rings that go further when you're starting from zero than they will later, so redeeming them first — rather than mid-session or after you've already built up some progress — gets more value out of the same reward.
Equip Vengeance as soon as you can
Once the death-revive loop is running, gamestratwiki names one explicit build priority for new players: equip Vengeance whenever possible, since it's ranked S-tier and described as the ring that matters most for progression. Leveling adds a separate +1% Attack Damage per level on top of whatever your revive loop and rings are giving you, so gaining levels alongside deaths — rather than only farming deaths — compounds faster.
Round out your session with friends and daily rewards
gamestratwiki's sequence also recommends joining friends for XP and attack speed bonuses, completing Shadow Clash whenever it's available, and claiming daily rewards every time you log in. None of these require a specific level or gear check — they're free value you can layer on top of the core death-revive loop from your very first session.
