Questions players ask
When does the first boss spawn?
Wave 20, per allthings.how, rouniverse, nerdschalk, and roonby. Bosses repeat every 20–30 waves thereafter (community observation).
What are the named relics?
Community coverage names three: Fortune (coin income), Vitality (base health), and Sharpness (melee damage). Only the developer's phrase 'relics to craft new OP objects' is officially stated. The names are widely repeated but rest on a single source until the developer confirms.
What is the Fortune Relic recipe?
One community source (rouniverse) reports 10 iron shards + 5 wood shards. The wiki labels this [INFERRED-FROM-MECHANICS] until a second source or the developer confirms.
Should I sell duplicate relic shards?
No. Duplicate shards are the upgrade material — selling them strands your relics at their starting tier.
