Best Guide to Last War Survival Season 3 Week 4: Dominate the Golden Realm

The Oasis Project remains one of the main weekly progression tracks in Season 3 Week 4. Your milestone for the Week 4 chest is to greenify 100,000 tiles within your warzone, and cross-warzone tiles also count, so the event rewards alliances that keep expanding and spending stamina consistently instead of letting greenification idle.

Each greenification costs 10 Stamina and rewards Profession EXP. That matters because strong Profession Skill investment helps you gain more EXP efficiency, which is one of the cleanest ways to chase Top 10 ranking rewards such as Gems and Speed-ups. Greenifying can also expose hidden Artifacts, giving the event extra value beyond the chest requirement itself.

Spice War is the centerpiece of Season 3 Week 4. If you played Rare Soil Wars in Season 2, the structure will feel familiar, but now everything revolves around Spice. Players are split between the Golden Tribe and the Scarlet Legion, and each week you alternate between attacker and defender roles depending on the schedule.

The live battles happen on Wednesdays and Saturdays after the War Declaration, Invitation, Prep Stage, and Battle Stage sequence. Your Week 4 chest objective inside this system is to convert 100,000 total units into Desert Protectors, but the real strategic pressure comes from looting mechanics. If your Alliance Center is destroyed, your alliance loses 10 percent of its owned Spice. If outbuildings are destroyed, you lose 5 percent. In the first week of Spice Wars, that can add up to a 20 percent resource loss, so base defense is not optional.

Pyramid War is the major kill-based event of Week 4. Your chest target is to kill 100,000 enemy units from other warzones, and the simplest way to finish that efficiently is to be active during Saturday's Spice War battles, where cross-warzone PvP naturally piles up the required kills.

The reason to care about rank, not just completion, is the reward pool. Top-tier Pyramid War rewards include Universal Exclusive Weapon Shards, which are among the most valuable upgrade items in the game for building hero exclusive weapons. Week 4 also opens the Level 7 City, the Capital, which pushes alliances toward Sunday's Capital Conquest and turns the late-week battle schedule into a connected progression chain.

Week 4 is not only about the new wars. It is also the point where players who stay disciplined on recurring systems quietly build a resource edge. Return of the Dead officially ends on the Friday of Week 4, so if you still need value from that event, the window is closing.

Sandworm Hunter remains unchanged, and almost everyone should participate daily because discovery and damage rewards go out by mail to a very large number of players. Desert Treasure is still one of the most important Mithril sources in the early season, so keep using hammers for both Alliance Vault and Personal Vault progress. Trade War also keeps moving, with Level 2 Trade Posts opening on Tuesday and still being captured by individual players rather than alliances.

Desert Bazaar should still be used like a weekly bottleneck solver rather than a random convenience shop. In Week 4, the strongest priorities are Overlord Chests, Compasses, Hammers, Speed-ups, and Landmine Refills. Those purchases all connect directly to active events instead of sitting in storage without helping your weekly plan.

The timing matters because the Bazaar refreshes at the start of every week. Players who spend casually on lower-value items often run short exactly when Sandworm Hunter refills, vault progression, or high-pressure battle prep starts demanding more support materials.

Hero progression choices can swing Week 4 harder than many players expect. If you are promoting UR heroes such as Scarlett, do not do it the moment the shards arrive. Wait for Thursday's Training Heroes day so the promotion also pays out through the daily arms race and VS scoring windows.

Hero Swap is the real efficiency tool. It allows you to transfer EXP and star levels between two UR heroes, which means an unused five-star hero can instantly become fuel for a new frontline plan. If you want Scarlett to become your main tank and you have a built but underused hero such as Carlie, Hero Swap is the fastest way to pivot your squad without rebuilding everything from zero.

Desert Blessing is also worth monitoring because seasonal buffs can become much more relevant when heroes such as McGregor receive new exclusive weapon support. That does not change the Week 4 core plan, but it is the kind of detail that separates efficient rosters from lazy ones.

Season 3 Week 4 is where casual play starts falling behind disciplined coordination. The week rewards alliances that keep greenification active, defend structures intelligently in Spice War, farm kills during the correct battle windows, and keep secondary systems like Desert Treasure, Trade Posts, and Hero Swap aligned with the bigger plan.

If you want the simplest rule set for the week, use this: spend stamina toward Oasis Project milestones, defend the Alliance Center first during Spice War, collect Pyramid War kills during Saturday battles, keep the Bazaar focused on real bottlenecks, and save UR promotions for Thursday so your progress also wins event points.
