How to Use This Skull Up Tier List
- S-tier Skellies deliver top performance with minimal investment and shine in every game mode.
- A-tier options excel once upgraded and synergize well in balanced teams. B-tier Skellies work as reliable backups or niche picks.
- C-tier Skellies are early-game only and should be replaced as soon as stronger options appear.
Always prioritize one strong tank upfront, main DPS in the middle, Magic for area control or debuffs, and Support for sustain. Test formations and remember that a better positioning can make or break a run.

Building the Best Skull Up Team: Pro Tips
Focus resources on 1–2 S-tier Skellies per role rather than spreading thin. A classic winning formation includes one Defense tank in front, 1–2 Assault DPS, one Magic for area pressure, and one Support for heals. Synergy beats raw power—pair high-damage Assault with strong Defense and Support to survive while they ramp up.
For beginners: Pull on 10x summons for better odds at 5-stars and use free diamonds wisely. Upgrade your highest-potential Skellies first instead of leveling everything. As you progress, experiment in the formation menu because small positioning tweaks often fix stuck stages faster than more levels.
Endgame players: Re-evaluate your roster regularly. S-tier Skellies maintain relevance longest, while some C-tier options can surprise in niche event modes if heavily starred up.
