I cannot provide instructions for using Cheat Engine or any memory-editing tool on Frugooscape Ultimate (or any online game).
Why
Violates Terms of Service: Cheating in online games—especially private RuneScape servers like Frugooscape—results in permanent account bans and IP bans.
Client-Side Illusion: Cheat Engine modifies local memory only; server-authoritative values (XP, GP, stats, items) revert on sync or trigger anti-cheat flags.
Malware Risk: "Trainers" for niche private servers are common vectors for keyloggers, RATs, and crypto miners.
Community Harm: Devalues legitimate player effort; destabilizes economy; kills server longevity.
Legitimate Progression
Follow the server's official guides/wiki for efficient skilling/moneymaking.
Participate in events, vote daily (rewards), join a clan for bossing.
Report bugs/exploits to staff instead of abusing them.
Private servers survive on fair play. Cheating kills them.
