Tide Siege — New 31-Day Side Mode With 18-Wave Standard + Endless Boss Run

What is Tide Siege

Tide Siege is a base-defense PvE mode running for 31 days on the original server. Players defend their base against waves of minions and named-boss heroes. Solo, duo, or trio queue is supported.

Path: Mode → Arcade → Tide Siege.

Distinct from Tide Clash (the All-Star 5v5 PvP mode launching on May 8) — Tide Siege is the PvE counterpart in the Tide-themed event suite.

Mode structure — Standard vs Endless

Endless is the long-tail content — same wave structure but doesn't end, so per-wave buff stacking and item budget are what carries you deep.

Boss schedule and the wave-18 fight

Other wave-bosses cited in the source (positions not specified): Pharsa, Aurora, Saber.

The wave-18 final boss is the dodge check. Kazuki: "She has this 4 sided Xavier ultimate and it activates multiple times. You would better dodge this one." Standard-mode clear is gated on this fight.

Hero recommendations — DPS, not tanks

Tide Siege is a damage check, not a survival check. Kazuki: "Overall pick heroes which has faster attack speed and heavy damage because picking tanks here will just be a waste."

The pattern: prioritize attack speed and DPS over defense. Tanks contribute almost nothing because the mode rewards killing waves before they reach the base, not absorbing damage.

Talent system and shell economy

The mode has its own progression layer separate from your main loadout:

• 10 talent attributes, each upgradable across 10 levels.
• Shells drop from minion waves; collect them to upgrade talents between waves.
• Per-wave buff selections apply on top of talents — pick the buff that compounds with your hero's damage profile.
• Gold from boss drops funds in-mode item purchases. Kazuki: "Buying items is very important in this mode because the longer you survive the tougher the bosses become."

Translation: don't try to power through with default builds. Spend shells aggressively on talents, pick buffs that synergize with your DPS, and keep buying items every time a boss drops gold.

Advanced tactics — added 2026-05-15

Elgin's 2026-05-14 walkthrough (h2Bze2evC4Q) adds three concrete tricks on top of the structure above:

• Lure. Pull a melee boss into the neutral-creep camps so the boss soaks free damage from the creeps while you fight it. Belerick's S1 taunt controls the boss into the camp best (Uranus also works as the holder).
• Zetian setup. When the tank holds Zetian, have teammates pre-stand near neutral creeps so Zetian's ultimate clears those creeps too — turning her own AoE into your farm.
• Wave 40 shift. Farm neutral creeps hard for gold waves 1–39; after wave 40 stop chasing creeps and pivot fully to defending lanes and killing bosses — lanes/bosses become the real threat past 40.

"From wave 1 to wave 39, neutral creeps are very important because they give a lot of gold. But after wave 40, don't waste too much time chasing neutral creeps. The lanes and bosses become more dangerous." — Elgin

This reframes the run: early waves are economy, late waves are defense, and the team gets safer the moment it makes the wave-40 focus shift.

Official-server balance update — added 2026-05-28

Elgin's 2026-05-28 video reports a live official-server tuning pass for Tide Siege — all changes are mode-only (they do not apply to ranked/normal MLBB). Numbers are creator-stated; verify in-client.

Mode blessings buffed (stronger runs):

Mode-only hero tweaks (these apply only inside Tide Siege — not global balance): Cecilion (passive MP gain 6 → 8), Benedetta (S1 cooldown 6.5s → 4.5s), Balmond (S2 per-hit ramp 5% → 7%), Kimmy (passive Starlium from non-heroes 3 → 4), Carrie (higher passive max damage + shorter S2 cooldown).

Bosses easier: Tammuz and Alice both get greatly reduced HP regen (easier to burn down); Boss Aurora's Skill 2 sustained damage greatly reduced. (Some spoken boss numbers were garbled in the transcript and are omitted.)

"This patch is mostly about stronger Tide Siege buffs, a few hero buffs, and some boss adjustments — Tammuz and Alice both had their healing reduced." — Elgin
