BRIGANDINE ABYSS — Rally & Support: How it works, the cost, and when to use

Using the Support command lets a Leader have one Monster join them and grant that Monster’s support ability (often referred to as a Rally Trait in Producer Letters). This is a tradeoff: the selected Monster is no longer acting as an independent battlefield unit, so you exchange that active body for the Trait. Official examples (NIS America System): Dragon — Movement +1; Pixie — Recover 5% of MP at the start of each turn; Demon — allied units become Dark element but Magic Defense decreases by 20%.

1. Prepare a squad with a Leader and up to five Monsters (squad size and formation are set by the Leader in the system text).
2. Use the Support command to select one Monster from the Leader’s squad to “join” the Leader and grant its support ability.
3. Once selected, the Leader gains the Monster’s support ability (Rally Trait) while that Monster no longer functions as an independent battlefield unit.
4. Play the battle with the Leader carrying that Rally Trait; evaluate whether the Trait’s effect is worth the missing active unit.

Note: the System page uses the term Support System / Support command; Producer Letters describe the mechanic as Rallying and use Rally Trait terminology. The steps above reflect confirmed system wording rather than unknown UI labels or undocumented mid-battle rules.

• It joins the Leader and grants its support ability (explicitly described on the official System page).
• It stops acting as an independent battlefield unit for the duration of that choice — you lose that Monster’s separate turn, movement, and direct actions while it is joined to the Leader.
• Official System and Producer materials do not confirm other UI-specific consequences (for example, exact dismissal costs, mid-battle swap rules, or whether the Monster can be targeted separately).

• The Leader receives the selected Monster’s support ability — referred to in Producer Letters as a Rally Trait.
• Rally Traits are varied: mobility, resource recovery, elemental changes, or tradeoffs that alter stats or resistances.
• The effect is applied to the Leader (and, where the Trait text specifies, to allied units) per the support ability’s description.

All three examples below come from the NIS America System text.

• Dragon — Movement +1
• Pixie — Recover 5% of MP at the start of each turn
• Demon — All allied units become Dark element, but Magic Defense decreases by 20%

(Producer Letters use the terms Rallying and Rally Trait when discussing additional monster traits. Use Producer Letters for more Rally Trait names when they are explicitly attributed.)

Choose Rallying when the Rally Trait provides a tactical effect that outweighs losing an active Monster body. Common situations:

• Mobility needs: Movement +1 (Dragon) lets a Leader reach objectives or reposition more reliably on tight maps.
• Sustained resource usage: Pixie’s Recover 5% of MP can justify losing a body for long fights that require frequent skills.
• Specific strategy synergy: a Rally Trait that directly enables your Leader’s planned tactics (for example, enabling a one-turn objective capture, escape, or repeated skill use).
• Puzzle or choke maps where one stronger Leader with enhanced movement or recovery is more valuable than an extra independent unit. Link: see /combat-tips/ and /classes/ for tactical context.

Keep the Monster as an independent unit when:

• Your squad needs its raw combat contribution (damage, tanking, ranged support) on the field.
• You require the additional positioning flexibility from having a separate body to occupy/contest tiles.
• The Rally Trait imposes a meaningful tradeoff (for example, the Demon trait’s defense penalty) that reduces your overall survivability.
• You are unsure whether the fight will last long enough for a recovery Trait or mobility gain to pay off.

For Monster role evaluation, compare the Rally Trait against the Monster’s expected independent value — see /monsters/ and /best-monsters/ for unit profiles and role testing.

• Treating Rally as a free passive buff: it is not — the selected Monster is removed as an independent unit.
• Choosing a Rally Trait without checking the tradeoff (for example, Demon’s Magic Defense penalty).
• Assuming Rally/Support will always be available mid-battle — official System and Producer materials do not confirm mid-battle swap or release mechanics.
• Building a squad that relies on both the Monster’s independent actions and its Rally Trait simultaneously (you can’t have both at once).

• Official System page name: Support System; it describes the Support command that lets a Leader have one Monster join and grant a support ability.
• Producer Letters refer to the same mechanic using the words Rallying and Rally Trait.
• Do not invent a single reconciled naming model that treats System and Producer Letter wording as different commands. Report both confirmed labels as they appear in those sources.
• The three Trait examples above are directly from the NIS America System text. Other Rally Trait names that appear in Producer Letters should be attributed to those letters when used.

Q: Does the Rallied Monster still take its own turns? A: No — the selected Monster is no longer acting as an independent battlefield unit while it is joined via the Support command.

Q: What are some confirmed Rally Trait examples? A: Confirmed by the NIS America System page: Dragon — Movement +1; Pixie — Recover 5% of MP at the start of each turn; Demon — allied units become Dark element and Magic Defense decreases by 20%.

Q: Can I swap Rally choices mid-battle or dismiss the Rallied Monster for free? A: Official System and Producer materials do not document mid-battle swap rules, dismissal costs, or exact release mechanics.

Q: Where can I find which monsters have Rally Traits? A: Producer Letters list additional Rally Traits; for unit-by-unit profiling, check /monsters/ and the Monster pages that cite Producer Letter attributes.
