Every module in the client, organized by category. This is the full Crystal PvP toolkit: end-crystal automation, anchor and bed detonation, trap detection, and potion and HUD combat aids — running natively on Fabric 26.2 and the classic 1.21.11 build.
Ten combat modules built around end crystals, anchors, beds, totems, and reactive switching. Everything you need to win the exchange.
Two-mode end crystal automation. Spray mode fires on hold for full-auto crystal spam with tunable break and place delays. Aim mode uses crosshair-based placement with separate intervals and kill-on-stop. The break-also option breaks and places in a single tick on dig packets.
2 ModesClient-side crystal death prediction. Removes crystals instantly after you swing without waiting for the server. The Marlow engine operates at the packet level and respects weakness and strength effects; the Client engine removes on attack events.
2 EnginesSwings the instant an enemy crosses your crosshair. Virtual mode simulates the mouse for a cleaner look; Direct mode fires attack packets straight at the server for maximum speed. Configurable hitbox range and cooldown.
Virtual / DirectKeeps a Totem of Undying locked in your offhand and swaps in a fresh one the instant it pops. Never die to a crystal with an empty offhand again.
Refills your totem slot from inventory into a configurable hotbar slot. AutoSwitch jumps to the totem slot, CheckHotbar searches your hotbar too, and InvOpen only restocks while your inventory is open.
ConfigurableDrives respawn-anchor and bed detonations. Marlow mode auto-activates charged anchors when your crosshair is on them. Packet mode intercepts block-interact packets and juggles glowstone and anchors to charge and detonate.
2 ModesPulls out your shield the instant incoming damage registers, then swaps back. Reactive defense that keeps you alive during crystal and melee trades.
Hot-swaps to end crystals in your hotbar the moment it is time to place. Seamless offensive switching so you never miss a crystal place.
Grabs obsidian automatically for quick blast shielding and crystal perches during combat. Build platforms and trap opponents without manual slot switching.
Flags hostile trap and burrow setups, highlighting unsafe crystal, anchor, and bed positions before you step into them. See danger before it detonates and keep control of the trade.
NewTwo movement modules for speed and positioning advantages in end-crystal fights.
Permanent auto-sprint so you are always at full speed between trades. Essential for closing distance and repositioning in crystal PvP.
Creative-style flight with a configurable speed slider. Fly freely in any direction for fast positioning across the battlefield.
Eight render modules for HUD overlays, visual clarity, and identity protection. The combat HUD is fully draggable and scales with your GUI settings.
Lists every active module on your HUD in a draggable overlay so your loadout is always in view at a glance.
Washes out all darkness and shadow effects. See everything at maximum brightness regardless of light level, dimension, or time of day.
Kills the camera shake and tilt when you take damage. Keep your aim locked during intense crystal trades.
Swaps your chat name for a configurable fake alias so your real IGN stays private. Default alias: Marlowww.
Toggles your cape on or off from inside the client without going through skin settings.
Spoofs or hides the latency other players see next to your name in the tab list.
Retimes your swing animation for a different visual cadence. Customize how your hits look in-game.
Shows potion effect timers and combat readouts on screen so you always know your buffs mid-fight.
NewTwo utility modules for quality-of-life and client management.
Clicks respawn the moment you die so you rejoin the fight instantly without any downtime.
The VapeLite-style menu for toggling and tuning every module. Toggle with Right Shift. Category tabs, module toggles, settings panels, and draggable HUD elements. Switch dark and light skins with the #theme command.
