Season 4 Guide
The Ultimate Last War Survival Season 4 Week 3 Guide: Sarah UR, Trade Posts & Faction Strategy
Prepare for Season 4 Week 4 with Sarah's UR promotion, rotating Trade Posts, Blood Night Hunter profession skills, Adam's Exclusive Weapon Battle Pass, and the server-wide faction decision.
Season 4 Week 3 is the final major preparation window before the large server wars of Week 4. The week combines a powerful Aircraft-hero upgrade, new Trade Post tiers, daily Blood Night Hunter PvP, a focused Adam weapon pass, and a server-wide faction choice.
Use this guide to turn each reset into permanent progression: promote Sarah when it fits your roster, compete for the highest-value Trade Posts, unlock the profession skills that improve Hunter uptime and experience, and coordinate your faction decision before the battle order is locked.
Key takeaways
- Promote Sarah to UR for an Aircraft-wide attack buff and stronger World Boss damage.
- Plan around Tuesday and Friday Trade Post openings, saving your strongest competition for Level 3 and Level 4 rewards.
- Reach Profession Levels 60, 65, and 70 to unlock Blood Night Hunter transformation, teleport, and Profession EXP bonuses.
- Treat Adam's $19.99 Exclusive Weapon Battle Pass as a targeted unlock-and-Level-2 package rather than a general resource pass.
- Choose your server faction with alliance leadership based on whether you prefer attacking first or defending first.
Part 1: Week 3 Priorities Before the Week 4 War
Week 3 is about converting seasonal activity into a stronger account before the major server-war phase begins. Sarah's promotion improves Aircraft output, Trade Posts add a dependable source of weapon and Overlord materials, and Blood Night Hunter skills reward players who invest in the profession tree.
The Week 3 event screen is also your reminder to check Goals, Grouping, Rules, Tactics Cards, and Rewards every day. Use those panels to confirm the current reset, claim available milestones, and coordinate alliance activity around the next Trade Post window.
- Check the event schedule after each daily reset.
- Reserve alliance combat strength for the Friday Level 3 and Level 4 Trade Posts.
- Finish profession-tree prerequisites before the busiest Blood Night rounds.
Part 2: Sarah UR Promotion — The Aircraft Version of Mason
Season 4 Week 3 unlocks Sarah's promotion from Legendary-ready progression into UR rarity. Sarah is an Aircraft hero, and the promotion gives her a role similar to Mason's value for another troop type: reliable area damage plus a team-wide offensive contribution.
Her promoted Airspace Supremacy skill is listed at Level 30/30. It attacks all enemy units for 286.40% Physical Damage, increases the Attack of all allied Aircraft heroes by 15% for 9 seconds, and also boosts the attack of back-row heroes. That combination makes her especially attractive for damage checks and World Boss rotations.
Sarah may not replace the strongest top-tier PvP specialists in every lineup. Her cleave damage and Aircraft/back-row buffs are nevertheless highly valuable for World Boss damage, PvE progression, and any roster that already invests in Aircraft heroes.
- Promote Sarah when you can support her with an Aircraft-focused lineup.
- Use her around short burst windows where the 15% Aircraft Attack buff can affect the full damage cycle.
- Prioritize her for World Boss testing before changing a proven PvP formation.
Part 3: Trade Posts — Tuesday and Friday Rotation
Week 3 opens all Trade Post levels and creates a predictable twice-weekly competition loop. The first set opens on Tuesday, while the second set opens on Friday and includes the high-tier Level 3 and Level 4 posts. The posts continue to rotate and reopen on those weekdays.
There are now two Trade Posts per day, giving each Warzone eight Trade Posts to contest. That wider distribution creates more combat opportunities, but alliances should still coordinate targets instead of splitting marches randomly across low-value fights.
- Plan for Tuesday and Friday openings rather than treating Trade Posts as random spawns.
- Coordinate rally timing, march power, and target assignments in alliance chat.
- At Level 4, the 50 Weapon Shards are limited to 5 per person, so track member claims before the post closes.
| Trade Post | Week 3 store focus | Best planning use |
|---|---|---|
| Level 1 | Weapon Shards are now available | Use spare participation windows for accessible shard income |
| Level 3 | Weapon Shards and new gorilla items | Prioritize the Friday rotation when your alliance can contest efficiently |
| Level 4 | Up to 50 Weapon Shards, 50 Training Certificates, Overlord Supply Chests, and Universal Overlord Shards | Save your strongest marches and alliance coordination for the maximum-value post |
Part 4: Blood Night Hunter — Profession Levels 60, 65, and 70
Blood Night Hunter becomes a daily PvP focus in Week 3. During the Blood Night event, Doom Walkers (also described as Samurai elites) move around the map. Players who can transform into a Blood Night Hunter can summon these targets and use the event to pressure other players.
The transformation and its follow-up skills are gated by the Profession Tree. Reaching the thresholds below is therefore a direct preparation goal for players who want more mobility, more targets, and more Profession EXP during each round.
- If you are below Profession Level 60, prioritize the tree before expecting to use the Hunter transformation.
- At Level 65, use the independent teleport cadence to keep pressure on moving targets.
- At Level 70, plan around the five-elimination daily cap so you do not over-invest after the EXP limit is reached.
| Profession level | Unlock | Why it matters |
|---|---|---|
| 60 | Blood Night Hunter transformation | Allows you to become a Hunter and summon Doom Walkers/Samurai elites |
| 65 | Blood Night Hunter Teleport | Grants 1 teleport count every 60 seconds; One More Time does not affect this count |
| 70 | Hunting Inspiration | Awards 30,000 Profession EXP for each Blood Night Hunter eliminated, capped at 5 per round/day |
Part 5: Adam's Exclusive Weapon Battle Pass
Adam's Exclusive Weapon Battle Pass is priced at $19.99 and is a focused purchase for players who want to complete Adam's unlock and start his weapon progression immediately.
The pass instantly grants 30 Adam Hero Shards and 70 Exclusive Weapon Shards. That is enough to unlock Adam if you do not already own him and take his Exclusive Weapon directly to Level 2. It is not overloaded with general progression materials, so evaluate it as a targeted hero-and-weapon package.
- Buy only when Adam fits your planned formation or you specifically want the weapon milestone.
- Count the 30 Hero Shards against your current Adam progress before purchasing.
- Compare the guaranteed Level 2 weapon path with your other Week 3 spending priorities.
Part 6: Faction Awards and Server-Wide Alliance Strategy
The faction system again turns an individual alliance choice into a server-wide strategic decision. The two leading servers in the group first fight to determine which side they occupy. The remaining six servers then choose which faction to join.
Your choice determines the combat order: whether your faction attacks first or defends first, and consequently whether it attacks last or defends last in the later sequence. Neither option is universally correct. A coordinated server should choose the order that matches its strongest rally timing, defensive coverage, and willingness to make a late-game push.
- Discuss the decision with server and alliance leadership before the selection window closes.
- Choose Attack First if your coordination is strongest in an aggressive opening sequence.
- Choose Defend First if your server is better at holding lines and converting a later counter-push.
- Share the final decision clearly so every alliance prepares for the same battle order.
Final Checklist: Turn Week 3 Into Week 4 Readiness
Season 4 Week 3 rewards preparation more than rushed spending. Promote Sarah and test her World Boss contribution, schedule Trade Post marches for both weekly openings, reach the next Blood Night Hunter profession threshold, and decide whether Adam's pass supports your roster. Then lock the faction plan with your server leadership.
By the end of the week, you should have a clear combat order, a stockpile plan for Overlord materials, and an alliance routine that can carry directly into the all-out war of Week 4.
- Sarah promotion and Aircraft lineup reviewed.
- Tuesday and Friday Trade Post assignments posted.
- Profession Level 60/65/70 progress checked.
- Adam Battle Pass value compared with your roster and budget.
- Faction choice communicated server-wide.
