Decide what you are saving for
Pick the character or weapon you actually want and save for it. Spending currency on every banner guarantees you end up with a wide roster of units you have no resources to build, which is strictly worse than two fully built teams.
Understand pity before you pull
Most of these games guarantee a high-rarity item within a published number of pulls, and many carry pity between banners of the same type. Check the in-game details screen for the exact count rather than relying on community summaries — the number is displayed in-game.
Build two teams, not six characters
Endgame modes usually need two teams. Two complete teams with correct artefacts or echoes outperform six half-built characters. Finish one team before starting the third.
Resin, energy, and daily caps
A capped regenerating resource gates progression. Always spend it down before it caps — capped resources are lost progression. Prioritise the materials your current team needs next, not the highest-level domain you can enter.
Artefact and gear discipline
Upgrade only pieces with the right main stat, and stop at the point where the sub-stat rolls turn bad. Feeding a mediocre piece to +20 is the most common way players run out of upgrade material. Salvage or recycle the rest.
Do not chase weapon banners early
Characters change how a team plays; weapons mostly change numbers. If you are free-to-play, the character usually gives more value per pull. Check the in-game banner details for the featured rates before committing.
Events are the main income
The majority of free currency comes from limited events and story content, not from dailies. If you have limited play time, prioritise events over repeatable farming.
Set a spending rule in advance
If you choose to spend, decide the amount before a banner you want goes live. The store page lists whether in-app purchases are present; treating them as a fixed subscription-style budget is far safer than deciding in the moment.
