The Port Mafia Building is a Base facility where you can upgrade Port Mafia areas in order to receive ATK and HP boosts for your units in combat. Each area boosts a specific attribute:
| Area | Character | Affinity |
|---|---|---|
| Office (å·å室) | Mori | Light |
| Cafeteria (é£å ) | Ozaki | Emerald |
| Armory (ę¦åØåŗ«) | Akutagawa | Dark |
| Armory (ę¦åØåŗ«) | Higuchi | Azure |
| Lab (ē ē©¶å®¤) | Kajii | Crimson |
Area effects do not apply to Friend or Guest characters. You can check active effects from the Status details in the team editing screen.
Power up materials or Ability Stones are used to upgrade the areas. Paying 5 Ability Stones will increase the area's EXP by 125,000. Excess EXP carries over to the next level. Every 10 levels, a set of evolution materials will be required to continue upgrading. Each area accepts only materials corresponding to their boosted affinity (excluding even neutral-affinity materials).
Upgrade Requirements[]
Evolution materials are shown as Crimson in the below table for ease of visualization, but each area would require materials of the matching affinity instead.
