Invincible: Guarding the Globe: How to Star Up Heroes

To star up heroes in Invincible: Guarding the Globe, you must consume duplicate hero copies to promote your units to higher star ranks. Starring up increases base stats and raises the character level caps that eventually stall your progress.

Your immediate priority is to concentrate duplicate copies on one or two main damage carries, then expand to your core five-hero combat squad. Avoid upgrading every character evenly across your roster.

How the Star-Up System Works

When you acquire duplicate hero cards from recruiting, save them to use as ascension material rather than spending resources indiscriminately. Promoting a hero provides two primary benefits:

• Increased Base Stats: Boosts damage output, survivability, and utility for campaign battles and GDA Ops.
• Higher Level Caps: Allows heroes to continue leveling up past standard level ceilings that block experience gains.

Before merging hero copies, open your collection and review the precise copy requirements for the character's next star threshold. Holding copies in reserve ensures you can immediately promote key units as soon as you meet the target requirements.

Hero Ascension Priorities

Because duplicate hero copies are limited, focus your investments on characters that yield the highest immediate power returns for your team.

1. Primary Carries: Allocate your initial duplicates to your primary damage dealers and high-utility team anchors.
2. Main Combat Squad: Build up your core five-hero team to stabilize progress in main campaign encounters.
3. Synergy and Faction Leaders: Focus on heroes that benefit from faction bonuses and fit long-term squad compositions.
4. Accessible Units: Invest in heroes currently featured in banners or frequently drawn from pulls so your star progression does not stall on rare drops.

Upgrading Strategy and Avoidable Mistakes

• Focus on your top five heroes first: Upgrading an entire roster simultaneously results in underpowered units that struggle in harder GDA Ops. Keep your resources concentrated on your primary team before upgrading secondary characters.
• Avoid over-investing in temporary filler: Upgrading easily accessible, low-tier units over long-term core heroes wastes valuable duplicate materials.
• Check copy requirements before merging: Merging duplicates into low-priority heroes can leave you short on materials when you pull a high-tier character that needs immediate ascension.
