System Client Mod (1.21.11, 1.21.1) – Powerful CPVP Ghost Client

System Client Mod is a customized fork of the Argon client (approximately 75% based on the original), focused on:

• Bypassing Vulcan and Grim Anticheat with advanced packet handling and human-like behavior simulation
• Improving graphics behavior, PvP usability, and overall stability under common anticheats

Features:

• Legit Autototem (HoverTotem-like)
  • Dynamic delay to simulate human-like behavior
  • Removed unstable autoswitch behavior from the original Argon
• Dhandmod Integration
  • Autoswitch-style logic without pad packets or impossible timings
  • Avoids impossible slot actions and inhuman delays
  • Custom totem slot selection
  • Configurable automation timings
• Misclick Optimizer
  • Rewritten and extended from the original Argon version
  • Reduces suspicious multiaction patterns and packet order issues
  • Best paired with AutoCrystal and Anchor Macro
• KeyPearl Enhancements
  • Switch-back slot selection for faster double-tapping and pearl usage
  • More controlled and predictable pearl behavior
• Placement Optimizer
  • Faster crystal placement when used with AutoCrystal
  • Removes extra placement delay to improve responsiveness
  • Quick block-up support for crystal PvP
  • Anchor exclusion option for more natural Anchor Macro usage
• Combat Behavior
  • Timed attack logic tuned for crystal and sword PvP
  • Internally evaluated across common combat scenarios for consistency
• Target HUD Improvements
  • Cleaner, more compact HUD design
  • Displays additional opponent information for clearer PvP decisions
• Camera Optimizer
  • Improved camera handling for PvP
  • Water and lava visual optimizations
  • Designed to work smoothly with freelook-type mods
• Screenshare-Oriented Utilities
  • Self-destruct functionality derived from Argon concepts to reduce screenshare risk
• Various small adjustments for smoother behavior under modern anticheats

User Interface

• Clean, modern GUI with an emphasis on readability
• Intuitive controls and compact layout to surface key information quickly

Configuration Guidelines – Grim Anticheat

• Suitable for large servers running Grim AC.
• Avoid:
  • Blatant autototem modes
  • AutoCrystal below 2 ticks for break and place
  • Anchor Macro with extreme (0-tick) settings
  • Break Optimizer and aggressive Jump Optimizer settings
  • Totem offhand setups that appear unnatural
• Use with caution:
  • Dtap setup modules
  • Anchor spam combined with aggressive air placement logic
• Recommended for safer behavior:
  • Auto XP with a non-zero delay
  • Misclick Optimizer enabled with all subfunctions
  • Placement Optimizer configured to exclude anchors
  • Moderate, non-zero delays for timing-sensitive modules

Configuration Guidelines – Vulcan & Other Anticheats

• Applicable for servers using Vulcan and similar anticheats.
• Most modules are generally usable with conservative settings.
• Safe starting point is to reuse your Grim configuration and then gradually relax limits.
• Safer extra options:
  • Anchor Macro with default timing
  • Dig Optimizer and Jump Optimizer with moderate values
  • Dtap setup modules when tested per server

Anticheat Test Summary

The following values are reported bypass rates under specific tests and configurations (actual results may vary by server setup):

• Grim AC: 90% reported bypass rate
• TotemGuard: 100% reported bypass rate (without auto offhand and blatant autototem)
• Vulcan AC: 98% reported bypass rate
• Matrix AC: 90% reported bypass rate
• Verus AC: 100% reported bypass rate
• Spartan AC: 100% reported bypass rate
• AAC: 100% reported bypass rate

Note: System is an Argon-based client with extended utilities and refined modules, intended to reduce anticheat flags and improve PvP control when configured responsibly.
