Why HQ Level Matters

Your Headquarters (HQ) is the backbone of your progression in Last Z. Increasing your HQ level opens the path to stronger heroes, buildings, troops, research, and late-game content.

Hero Level Cap

Every HQ level adds +5 to your hero level cap.

This makes HQ progression directly connected to the strength of your heroes.

Sophia — The Queen of Construction

Sophia is especially valuable for players planning long-term HQ progression.

Her 3rd skill provides construction benefits including:

• Extra free construction duration
• Faster construction speed
• 4 Stars: Resource cost -5%
• 5 Stars: Resource cost -10%

The Goal

Try to have Sophia at 5 stars before making the expensive HQ30+ push.

Her bonuses apply across your building upgrades. Since HQ progression forces you to upgrade prerequisite buildings along the way, those savings can add up.

When a Second Builder Helps

A second builder allows you to upgrade two buildings at the same time.

It is most useful when prerequisite buildings are holding up your next HQ upgrade and you have enough resources to keep both construction queues working.

A second builder does not:

• Shorten an individual construction timer
• Remove building prerequisites
• Reduce the resources required

Use the additional queue strategically rather than upgrading unnecessary buildings simply to keep it occupied.

Secretary of Construction

The Secretary of Construction Capital position provides:

+15% Construction Speed
+1 hour Free Construction Duration

When available, this can provide another useful boost before beginning major construction.
