The encounter’s normal Gold reward depends on whether Fat Gremlin escapes. If Fat Gremlin does not escape, the normal Gold reward is 100%. If Fat Gremlin escapes before Gremlin Merc stole any Gold, it is 50%. If Fat Gremlin escapes after any Gold was stolen, it is 0%. Stolen Gold is moved to Fat Gremlin as Heist, so killing Fat Gremlin returns that stolen Gold.
