The Best Guide to Last War Survival: Season 3 Week 3 Events, Strategies, and Tips

The Oasis Project continues in Week 3 and remains a reliable source of Professional Experience, Diamonds, Resource Chests, and Construction Speed-ups. It is not the flashiest event on the calendar, but it still supports your long-term season progression and skill unlock pace.

The routine is simple: find the border between grassy land and desert on the world map, tap the Greenify icon beside the target building, and send a scout plane to convert the surrounding tiles. If you ignore it because other Week 3 systems look more exciting, you can quietly fall behind on Professional Experience that matters later in the season.

Week 3 is when the Scarlet Legion versus Golden Tribe structure starts to matter. The two strongest warzones in a grouping become the faction leads, and presidents from other warzones decide which side to join. If a faction fills up, presidents can push another warzone out, so this system is only partly about raw power and heavily shaped by diplomacy behind the scenes.

Faction scoring comes from converting dead units into Desert Protectors, which also pays out Diamonds, Mithril, and Sacred Water. By this point in the season, some players may already feel overloaded with Mithril or Sacred Water, but the ranking pressure and long-term faction positioning still make the event worth coordinating closely.

Hero Promotion is one of the biggest Week 3 account spikes because this season lets players upgrade the epic hero Scarlett into a Legendary UR hero. That kind of promotion can easily become the centerpiece of your weekly plan, but the unlock path has two separate gates that catch unprepared players.

First, the server must collectively donate 3,000,000 coins before the Hero Promotion activity appears. Second, and much more important for individual readiness, you need the Curse Research Lab at Level 30 to obtain the promotion tokens required for Scarlett. Players who ignore Curse Lab progress can watch the event open and still fail to convert that timing into an upgrade.

Week 3 replaces the old Sandworm Crisis kill pattern with Sandworm Hunter. You are no longer solving the event by simply attacking worms. The entire loop shifts toward finding, trapping, and then capitalizing on higher-value Sandworm catches.

The first requirement is unlocking Trap Landmine in your seasonal profession skills, whether you are on the Engineer or War Leader path. Without that skill, you cannot place traps at all. Trap refills can come from storyline survivors visiting your base or from the Desert Bazaar using Sandworm Scales, so players who start stockpiling too late usually lose event tempo immediately.

There are separate daily rankings for Discoveries and Damage Dealt. Discoveries reward items such as Alliance Compasses and the Worm Master commemorative coin, while damage rankings can pay out universal exclusive weapon shards, resources, and speed-ups. A known bug has affected the Worm Expert tracking tab on some servers, so be prepared for tracking inconsistencies until the developer side is corrected.

Week 3 raises the map stakes by opening Level 5 and Level 6 cities. Level 5 cities begin opening earlier in the week after Doom Elites are cleared, while the Level 6 Square of Judgment unlocks on Saturday and becomes the headline alliance target.

The reason to organize around Saturday is simple: Level 6 fights carry some of the best seasonal loot, especially Hero's Return Recruitment Tickets that can convert into valuable legendary hero pulls. This is the part of Week 3 where scattered alliances get exposed and disciplined alliances pull ahead.

Trade War returns in a familiar format through Trade Posts. During the first half of the week, alliances can capture Trade Posts across any warzone and use them to buy goods with Diamonds. That gives Week 3 another reason to pay attention to territory pressure outside your immediate home route.

Captured posts enter a six-day protection cycle before becoming vulnerable again. That means early capture timing matters, especially if your alliance wants stable access to a post's inventory before rival players or alliances start contesting it.

Recurring seasonal systems still matter in Week 3. Desert Treasure remains important because Alliance Compasses from Sandworm Hunting can reveal Alliance Vaults, while Hammers break Personal Vault blocks to uncover artifacts and rewards.

Desert Bazaar should be treated as a bottleneck solver, not a random shop. This week, the highest-value purchases are usually Trap Landmine Refills, Hammers, and Compasses, because each of those feeds an active Week 3 loop instead of sitting in inventory unused. Desert Blessing is also worth checking so seasonal decorations and hero combinations continue giving passive buffs such as reduced monster damage taken.

Season 3 Week 3 is where short-term event execution starts feeding long-term faction control. Good alliances keep Oasis Project experience moving, settle faction politics early, unlock Scarlett's promotion path before it becomes urgent, and approach Sandworm Hunter as a preparation event instead of a simple combat event.

If you want the cleanest rule set for the week, use this: keep greenification running in the background, coordinate faction choices as soon as presidents can act, push Curse Research Lab to Level 30, unlock Trap Landmine before the first serious Sandworm Hunter push, and schedule your strongest attendance for Saturday's Level 6 City Clash.
