:fire: Oni Summon – What It Really Does & Why It Matters

If you’ve reached Season IV in Last War: Survival and unlocked the Oni Summon ability, you might be wondering:
What’s the point of using this skill if Oni Legions attack anyway?
Why are some players using it and claiming no rewards?

Let’s clear up the confusion and break down exactly how Oni Summon works, what benefits it brings, and how it differs from normal Blood Night encounters.

:video_game: What Is Oni Summon?

Oni Summon is a Profession skill unlocked from Day 15 of Season IV (Week 3), once your professional level reaches 100.

When activated:

  • It draws nearby Oni Legions to your active troops (for 5 minutes).
  • If your troops vanish or get wiped, the Oni will target the nearest bright base (yours or an ally’s).
  • You must then kill those Oni to receive the rewards.

But here’s the key:
This skill only works during Stage 3 of the daily Blood Night event.

:three_o_clock: When Does It Work?

:white_check_mark: Only during Stage 3 of the Blood Night event, which happens daily at:

  • 02:30
  • 10:30
  • 18:30 (server time)

If you use the skill before Stage 3, the Oni might still move, but you won’t get the benefits.

:gem_stone: What Are the Real Benefits of Using Oni Summon?

Here’s what sets summoned Oni Legions apart from regular ones:

:magnifying_glass_tilted_left: Aspect Normal Oni (no summon) Summoned Oni

:red_exclamation_mark:Common Misunderstandings

Many players think Oni Summon is broken because:

  • They activate it before Stage 3.
  • They don’t personally kill the summoned Oni (e.g. someone else does).
  • They forget to tap the loot screen after the kill.
  • They expect unique summon-only rewards (there are none — just boosted Blood Night drops).

In short:
:small_orange_diamond: It’s not a magic button.
:small_orange_diamond: It’s a high-efficiency farming tool for Stage 3 Blood Night only.

:white_check_mark: Tips to Use Oni Summon Effectively

  1. Use it only during Stage 3 (watch the countdown or check event time).
  2. Send out troops (to collect or assist) before activating the skill — Oni will lock onto them.
  3. After Oni are attracted, attack and kill them quickly (solo or rally).
  4. Don’t forget to collect your drops from the loot pop-up.

:brain: Final Thoughts

Oni Summon isn’t broken — it’s just misunderstood.

Used correctly, it’s one of the best tools in Last War: Survival Season IV to farm:

  • Tactic Cards
  • Magatama
  • Season mission progress

So next Blood Night, try summoning your own wave of chaos — just make sure you’re ready to fight it off and claim your rightful rewards.
