Last Fortress: Underground Ada Hero Build Guide

To maximize Ada's utility in Last Fortress: Underground, place her in the middle or back row of your formation, prioritize gear that reduces skill cooldowns, and fully upgrade her primary utility skill before investing in secondary passives.

Formation Placement and Role Setup

Ada operates strictly as a support unit rather than a frontline damage absorber or main damage dealer. Her main contribution comes from enabling team synergy and maintaining utility uptime during extended engagements.

• Recommended Row: Position Ada in the middle or back row. This shields her from immediate enemy targeting and gives her time to cycle abilities.
• Frontline Dependency: Always deploy Ada alongside durable front-line tanks. If your frontline falls early, Ada lacks the self-preservation stats to survive heavy direct attacks.
• Campaign Priority: If you are actively pushing early campaign stages, level your front-line defenders before spending rare high-level materials on Ada.

Skill Upgrade Priority

Ada requires focused skill medal investment to stay effective. Spreading skill medals evenly across all abilities reduces her ability to influence combat.

1. Primary Utility Skill: Maximize this ability first. Increasing this skill raises her core utility output and overall tactical efficiency.
2. Secondary Support Passive: Upgrade this second. Level it only after the primary utility skill is maxed to boost team-wide benefits.
3. Tertiary Damage and Defense: Keep these at base level. Avoid spending skill medals here unless you have a surplus of materials.

Gear Selection and Upgrade Order

Select gear that enhances Ada's ability to cycle skills quickly and maintain team uptime. Avoid builds that focus entirely on self-preservation stats or raw attack.

When upgrading Ada's gear, prioritize her weapon and tactical modules first. These slots provide the direct stat increases needed for her support abilities to scale into higher-difficulty content.

Team Synergy and Lineup Options

Ada performs best when paired with heroes who can either convert her support windows into raw damage or protect her from incoming fire.

• Front-Line Tanks: High-health tanks pull enemy aggression, keeping Ada alive long enough to use her skills.
• Burst Damage Dealers: Pair Ada with high-burst attackers who can exploit the control or utility windows her skills create.
• Crowd Control Specialists: Combine Ada with control units to extend total lockdown durations against opposing lineups.

Counters and Limitations

Ada is not a universal solution for every combat scenario. Recognize her performance limits before committing her to a lineup:

• High-Burst Enemy Lineups: Opponents capable of quickly eliminating back-row support heroes can defeat Ada before her skills activate.
• Skill-Cycling Debuffs: In high-level stages where enemies inflict debuffs that interrupt or delay skill usage, swap Ada out for a more specialized support unit.
