IDS GRAND ARENA / DEFENSIVE SCOUTING FILE

How to scout Emperor Palpatine with Starkiller

A complete 5v5 Emperor Palpatine defense can hide Starkiller's qualifying Omicron, Mara Jade control, a Jedi Tank's Damage Immunity and a late Force Energy finisher. Scout the exact five rather than treating all Palpatine-led teams as identical.

01 / VERIFY THE FULL DEFENSE

What team is actually in front of you?

The documented defensive five in the IDS Grievous/BB-8 attack file is Emperor Palpatine (Sith leader), Mara Jade (Dark Side Unaligned Force User), Old Ben (Jedi Tank), Visas Marr (Light Side Unaligned Force User healer) and Starkiller. These four supporting roles meet Starkiller's exact 5v5 four-class requirement when there is no Galactic Legend ally.

When the team changes

Other Palpatine teams may run Darth Vader, Royal Guard, Grand Admiral Thrawn or different support characters instead. Those variants do not necessarily activate Starkiller's four-role Grand Arena bonuses. Juhani or General Kenobi changes Jedi role or durability, and 3v3 uses a more permissive no-more-than-one-of-each condition; do not use a five-unit result for a trio.

Before attacking, inspect relic levels, ability tiers, each active Omicron and the actual Datacron. Defending a different five or a 3v3 trio can change what qualifies. Current Battle Records are a separate source from the mechanics on this page.

02 / THE CURRENT ABILITIES

Four mechanics that change your opening

EVIDENCE 01

Starkiller: check all four required role tags

At the start of a 5v5 battle, Starkiller needs exactly one Jedi, one Light Side Unaligned Force User, one Sith and one other Dark Side Unaligned Force User plus no Galactic Legend ally. The fully upgraded Unique increases Critical Damage, Max Health and Protection, grants Speed and immunity to Daze and Stun.

EVIDENCE 02

The Grand Arena Omicron changes Old Ben

When the four-role condition qualifies in GAC, Jedi Tank allies Taunt at battle start. When Starkiller uses a Special, Jedi Tanks get Taunt and Damage Immunity for one turn, while Light Side healers have cooldowns reduced. Damage Immunity cannot be beaten simply by adding damage.

EVIDENCE 03

Palpatine and Mara Jade create an opening control loop

Emperor Palpatine supplies Sith/Empire leadership and Shock/Turn Meter pressure; Mara Jade can inflict disruptive debuffs while helping set up Empire allies. The qualified Starkiller defense gains extra Speed, so check the exact opening before betting on your own fastest unit.

EVIDENCE 04

Force Energy and Size Means Nothing

Starkiller builds Force Energy when dealing damage. At 100 stacks he becomes Unleashed and may unlock Size Means Nothing with no Galactic Legend ally: a once-per-battle area attack that Stuns enemies, deals Max-Health-based damage and restores allied Health and Protection.

Omicron and Zeta bonuses above require the correct game mode, character tier and start-of-battle team composition. Do not assume a modifier applies to a character merely because it is commonly included in that squad.

03 / PRACTICAL BATTLE SCOUTING

Six decisions before spending the attack

  1. 01

    Confirm whether this is actually a Starkiller defense

    Palpatine plus Mara is not enough to conclude the four-role Starkiller Unique is active. Read every fifth slot and the Galactic Legend restriction.

  2. 02

    Verify the Omicron before using older advice

    If Starkiller's qualifying Grand Arena Omicron is installed, additional Speed, starting Taunt, counterassist effects and defensive triggers change your first action.

  3. 03

    Plan against Mara and Palpatine's control

    A fast Mara can disrupt the entire offense. Check whether your attacking unit can cleanse, resist, or survive the opening Shock and other debuffs.

  4. 04

    Avoid wasting a finisher on immune Old Ben

    Jedi Tank Old Ben can be Taunting and Damage Immune after Starkiller acts. Determine whether a buff dispel, a different target or a wait is the legal answer.

  5. 05

    Watch Force Energy rather than only Starkiller's Health

    Starkiller may reach Unleashed and use Size Means Nothing, which can Stun the whole offense and restore the entire defending team. A nearly won battle can reverse.

  6. 06

    Match your chosen attacker to a comparable recorded five

    The IDS Grievous/B1/B2/BB-8/MagnaGuard file is a specific historically observed example, not a universal answer. Compare the full five, relics, Datacron and match counts.

These are conditional scouting decisions, not a claim to have replayed a battle or an automatic turn-by-turn win. Record the first triggered mechanic that differs from your plan.

INTERACTIVE / TRUE BATTLE FORMAT

Check matching GAC history before choosing a counter

Use 5v5 evidence for five-unit teams and 3v3 evidence for trios. Match the full defender and attacker, relics, ability upgrades, Datacrons and number of observed battles. The static season labels represent reviewed historical seasons, not future live win rates.

INTERACTIVE / FAILURE DIAGNOSIS

What caused the attack to fail?

Select the first problem you observed, then check the qualifying ability text. This is a local research tool, not an imported battle log.

Old Ben has Taunt and Damage Immunity

Starkiller's GAC Omicron grants the Jedi Tank starting Taunt and refreshes Taunt/Damage Immunity after Starkiller uses Specials. Check targets and buff dispels.

Character-kit research is distinct from live win rates. IDS does not claim to have replayed specific matches, scanned private rosters, or guaranteed a result. Upgrades, Datacrons and future game seasons may change this advice.
