MONGIL: STAR DIVE Post-Summer Patch Tier Guide

To optimize your squad performance following the post-summer patch in MONGIL: STAR DIVE, focus your primary leveling materials and high-tier equipment on S-Tier carries like Summer Verna and Francis. Upgrading top-tier burst characters first maximizes damage during tag-team combat rotations and resolves bottlenecks in high-difficulty boss fights.

Post-Summer Patch Roster Hierarchy

The post-summer patch meta rewards high damage output, fast skill cycling, and strong tag-team swap synergies. Use this resource allocation framework to build a balanced party without wasting upgrade materials on lower-tier heroes:

Tier	Primary Role	Investment Priority	Recommended Focus
S-Tier	Primary Damage Carry	High (Primary gear & level materials)	Rapid skill cycling, burst damage, swap synergy
A-Tier	Support & Utility	Medium (Secondary gear & cooldown stats)	Defensive buffs, elemental coverage, crowd control
B-Tier	Niche Specialist	Low (Hold materials unless required)	Specific boss mechanics, early filler roles

S-Tier Investment Priority

S-Tier heroes form the core of high-level party builds. In the current patch environment, Summer Verna and Francis stand at the top of the roster because they combine elevated burst damage with strong team-swap utility.

Primary Resource Allocation: Direct all top-tier equipment, skill materials, and main level-up items to your S-Tier carry before upgrading secondary characters.
Skill Cycling and Rotation: Build around their high swap bonuses. Switching to an S-Tier carry during tag-team rotations maintains high damage output while your secondary abilities cool down on the bench.
Survivability and Phases: Upgrading S-Tier units improves their field uptime, giving your squad the durability needed to clear multi-phase boss fights.

Supporting Roles (A-Tier and B-Tier)

Once your S-Tier carry reaches a strong baseline, invest in secondary utility units to stabilize overall party combat.

A-Tier Utility Units

A-Tier heroes provide essential stability through defensive buffs, crowd control, and elemental coverage. While they lack the raw burst potential of S-Tier carries, their lower resource requirements make them efficient secondary investments. Focus secondary gear upgrades on reducing their skill cooldowns so they can continuously enable your main damage dealer.

B-Tier Specialists

B-Tier heroes fill situational needs or serve as temporary placeholders while expanding your roster. Avoid spending scarce upgrade materials on these units during early progression. Only invest in a B-Tier hero if a specific encounter requires their unique elemental alignment or specialized skill mechanics to bypass an obstacle.
