Resources are the input to every upgrade in Lost Tower. This guide covers where each resource comes from, which sources offer the best yield, and how to farm efficiently without burning out.
Marks come from milestones and daily missions. Shards come from wave completion. Essence comes from god-aligned matches. Gold comes from enemy kills. Each has efficient sources and inefficient sources. Knowing the difference is key to fast progression.
Quick answer
Match length drives Shards. Daily missions drive Marks. God alignment drives Essence. Active play drives Gold.
Marks: where to farm
Marks come from three sources:
- Milestone wave completion. Each new high wave (10, 20, 30, etc.) gives Marks once.
- Daily missions. Resets every day. The most reliable source.
- Weekly tournaments. Best Marks-per-hour rate available.
Skip your daily missions and you fall behind. The dailies matter.
Shards: where to farm
Shards come from wave completion. Higher waves give more Shards per wave. The fastest Shards-per-hour rate is from long matches reaching wave 40+. Short matches give worse rates.
Essence: where to farm
Essence comes from matches aligned with a specific god. Staying with one god maximizes that god's Essence. Switching between gods produces small amounts in each, which slows total progression. Pick one and commit.
Gold: in-match optimization
Gold is earned by killing enemies. To maximize Gold per match: focus on damage output (kills faster), play actively (manual targeting kills faster), and reach the high waves (later enemies drop more Gold).
