Alliance Exercise – Large Sandworm Guide

:scorpion: Alliance Exercise – Sandworm Crisis Event Guide

When your server enters Season 3 (and beyond), Sandworms permanently replace Marshal’s Guard tanks in the Alliance Exercise. Here’s an easy-to-follow breakdown guide.


:clipboard: Event Basics

  • Frequency: Every 2–3 days
  • Duration: 30 minutes
  • Goal: Rally against the central Large Sandworm, manage Small Sandworm spawns, and earn points for individual & alliance rewards

:snake: Three HP-Based Stages

The event advances when your alliance chips down the Large Sandworm’s HP past key thresholds:

  1. Stage 1 – Initial Assault (100 %→70 % HP) • Only the central Large Sandworm is on the platform. • Focus on establishing your rally rhythm and dealing steady damage.

  1. Stage 2 – Small Sandworm Phase (70 %→30 % HP)
    Small Sandworms begin spawning on random member bases.
    • Affected bases cannot dispatch new marches until the worm is cleared.
    • Ongoing rallies or queued marches will still complete, but you’re blocked from launching anything new until the worm is cleared.

Clearing options:

  • Kill it: Send any squad (solo march) from your base to defeat the Small Sandworm and collect its minor reward.
  • Teleport away: Instantly moves your base and removes the worm—no reward, but you rejoin rallies immediately.

  1. Stage 3 – Final Push (< 30 % HP)
    • Small spawns stop, and the Large Sandworm turns enraged.
    • Large worm attacks player’s bases. You can reinforce the targeted player base to repel the attack.
    • Rally damage ramps up to finish off its remaining HP.
    • Use your best buffs and squads for maximum points.

:bullseye: Difficulty Levels & Scoring – Sandworm Exercise

Before each Alliance Exercise begins, R4 or R5 officers manually select the Sandworm difficulty level, which determines the HP of the Large Sandworm and the potential rewards.

:bug: Difficulty Levels

  • Difficulty ranges from Level 40 to Level 90, increasing in increments of 10 (e.g. Lv. 40, Lv. 50, Lv. 60… up to Lv. 90).
  • Higher levels = more HP, stronger worm, and better rewards.
  • The selected level applies to the central Large Sandworm only.

:light_bulb: Tip: Choose a level that matches your alliance’s rally strength. If you can’t consistently deal 50%+ damage per rally, drop down a level next time.


:bug: Small Sandworm – Damage & Scoring Contribution

:white_check_mark: Do They Count Toward Points?

Yes, defeating a Small Sandworm does contribute to your personal score and overall event progress.

  • When you send a solo march to kill a Small Sandworm on your base, the damage dealt is counted toward your total event points.
  • The worm has a fixed HP pool (based on your server’s progression), and every point of damage equals 1 event point, just like with the Large Sandworm.
  • It helps reduce the Large Sandworm’s HP indirectly, as all damage dealt during the event is pooled for progression.
  • It counts toward the alliance’s total damage.

:light_bulb: Tip: If your squad defeats the Small Sandworm in one hit, you’ll earn full points for its HP value.


:key: Quick Strategy Tips

  • Squad Roles:2nd Squad → Rally launcher • Main Squad → Rejoins every rally for top damage
  • Stagger Launches: Begin 2nd-squad rallies at 30 sec intervals for the first 4–5 minutes.
  • Platform Proximity: March your base next to the rally portal so your main squad can rejoin every 2–3 minutes.
  • Small Sandworm kills: useful if rally slots are full or cooldowns are active
