Clear takeaways for your next run
Hold the Heart Locket through any playthrough. It quietly pays for itself when damage spikes. Treat it like a permanent upgrade.
Q: Can I sell the Heart Locket if I do not want it?
A: You can, but you waste a core survivability upgrade and lose healing flexibility.
Q: Does this apply to all Undertale soul items?
A: No, other soul items rarely compare; only the Heart Locket consistently outshines selling for gold.
