# Recommended stacks

> Pair Halt with packet hardening, vanilla patches, and one combat anticheat.

Halt is the **incident-response layer**. Pair it with packet hardening, vanilla patches, and a combat anticheat when those layers matter for your gamemode. Halt does not replace them.

Baseline for every stack:

* Paper (or Folia) with sensible book / item validation settings. Halt's jar is Java 17 bytecode; Paper/Folia **1.20.5–1.21.x** hosts need **Java 21**; **26.1+** hosts need **Java 25**. Folia 26.2 is experimental.
* Halt with alert-first defaults
* Discord webhook configured for HIGH/CRITICAL

## SMP / economy survival

| Layer             | Recommendation                                 |
| ----------------- | ---------------------------------------------- |
| Packet / crash    | LPX or ExploitFixer                            |
| Vanilla patches   | IllegalStack (tune carefully)                  |
| Combat AC         | GrimAC or Vulcan (pick one; do not stack both) |
| Incident response | **Halt**                                       |
| Rollback          | CoreProtect (or equivalent)                    |

## Skyblock / BoxPvP

| Layer             | Recommendation                                        |
| ----------------- | ----------------------------------------------------- |
| Packet / crash    | LPX or ExploitFixer                                   |
| Vanilla patches   | IllegalStack modules that match island/shop mechanics |
| Combat AC         | GrimAC or Vulcan                                      |
| Incident response | **Halt** — lean on DupeWatch + lockdown               |
| Rollback          | CoreProtect                                           |

## Lifesteal / PvP-heavy

| Layer                    | Recommendation                                                                            |
| ------------------------ | ----------------------------------------------------------------------------------------- |
| Packet / crash           | LPX or ExploitFixer                                                                       |
| Combat AC                | GrimAC or Vulcan                                                                          |
| Incident response        | **Halt** — MineWatch/FreecamWatch for abuse review; lockdown for active economy incidents |
| Client policy (optional) | Sentry / similar for banned clients                                                       |

## Minimal budget stack

| Layer             | Recommendation                                            |
| ----------------- | --------------------------------------------------------- |
| Packet / crash    | Paper limits + free ExploitShield, or skip if risk is low |
| Vanilla patches   | IllegalStack                                              |
| Combat AC         | GrimAC                                                    |
| Incident response | **Halt**                                                  |

## Coexistence rules

* Do **not** stack Grim and Vulcan.
* Prefer one packet firewall (LPX **or** ExploitFixer), not both.
* ExploitFixer may conflict with other packet listeners (HamsterAPI path). Follow that product's guidance.
* Halt stays on Bukkit-level signals and does not require PacketEvents, ProtocolLib, or HamsterAPI.
