Comet Azur is the biggest damage nuke in the game. Stars of Ruin is near-undodgeable tracking. Both are Intelligence endgame sorceries but serve completely different roles.
Comet Azur Build
Boss one-shots and burst damage
Strengths
- Highest burst DPS in the entire game
- One-shots many bosses with proper setup
- Satisfying kamehameha gameplay
- Terra Magica combo for 35% more damage
- The 'delete boss' button
Weaknesses
- Requires setup time (Terra Magica + Physick)
- Useless against mobile bosses
- Zero PvP viability
- Gimmicky — relies entirely on one combo
- Boring for some players
VS
Stars of Ruin Build
PvP dominance and consistent damage
Strengths
- Near-undodgeable tracking projectiles
- Works in PvP (best sorcery for duels)
- No setup required — just cast
- Consistent damage against any boss
- Pressure tool that forces reactions
Weaknesses
- Lower single-cast damage than Comet Azur
- Higher FP cost per cast
- Cannot one-shot bosses
- Somewhat spammy gameplay
- Less dramatic than the beam
Verdict
Comet Azur for boss one-shots in PvE. Stars of Ruin for everything else, especially PvP. Both builds use the same stats (80 Int) so you can have both spells memorized and use whichever fits the situation.
