Clear the tutorial and early Story stages before spending everything on a rare pull. Story shows how your account actually loses: enemies reach the base too early, a boss survives too long, or placement costs slow the board down. Once you can reach the summon area, upgrades area, Traits NPC, perks menu, and Crafting NPC, keep pushing Story until one of those problems appears.
The first Story stages teach unit roles. A damage unit clears waves. A tank or durable front unit buys time. A support or debuff unit helps difficult enemies fall before they cross the lane. A farm or economy unit helps you place more units during a match. A beginner team needs enough of these jobs covered to survive waves and bosses, not only the rarest names from the banner.
Early Gems work best with a role checklist. After a summon session, ask which job the account is missing: damage, survival, support, or economy. Keep a usable unit for each missing job before spending more Gems on low-rate targets. Selling every non-top unit can leave the roster clean on paper but weak against the next Story wall.
Perks come before deep trait rolls. Max Yen and Yen Generation change how quickly you can place and upgrade units during a run. Base Health matters when one leak ends a run that was otherwise stable. Pick the perk that matches the loss: money cap, income speed, or base deaths.
Trait Shards fit units that will stay in the lineup. The Traits NPC can reroll trait and sub-trait results together, so a good roll on a temporary unit loses value when the unit leaves your team. Roll traits when a carry, boss killer, tank, support, or farm unit already has a clear job. If an early carry gets a role-matching trait, run that power in Story before rolling again.
Gear crafting starts after the wearer is clear. Gear asks for materials and Gold, and recipes point you toward specific farming routes. The gear wearer, improved role, and material act range decide the route. A damage item belongs on a unit you place often; a tank item belongs on the unit that actually keeps lanes stable.
Active codes can give a starting boost when they are still valid. If a code gives summons, it can fill missing team roles. If it gives reroll resources, those resources fit a keeper unit. If it gives Gold, the best spend is the account upgrade that changes your next stage attempt.
After each loss, the next spend comes from the result. Early leaks point to placement timing, Yen, or a cheaper early unit. Boss losses point to sustained damage or a better carry trait. One fatal leak points to Base Health or a tank slot. Expensive units sitting unplaced point to economy. This keeps early progress tied to the stage instead of menu pressure.
