Alterna
Alterna is a spell from Ring of the Lucii.
If you have full MP, holding triangle and R1 (Control scheme A on PS4) makes Noctis cast Alterna. This affects all enemies on a large radius and has a chance to instantly kill each of them. That's right, it is RNG-based. There are no enemies that are immune to this spell.
Do any stats affect the kill chance? Well, that's a hard one. Testing this is a real pain because it's RNG, but I did some testing. I casted Alterna on a Red Giant 300 times.
- 100 times with 75 mag (level 1)
- 100 times with 794 mag (level 1)
1*00 times with 2203 mag (level 102)
Results can be seen here:
| Magic | Kills/Casts (first 50) | Kills/Casts (last 50) | Kills/Casts (total) |
|---|---|---|---|
| 75 | 17/50 | 22/50 | 39/100 |
| 794 | 21/50 | 19/50 | 40/100 |
| 2203 | 28/50 | 20/50 | 48/100 |
My analysis:
No difference between 75 and 794 magic. Very slightly better results with 2203 magic, but I'm willing to bet that's because of the good RNG with the first 50 casts. It doesn't seem like magic affects it at all.
There is the possibility that it's not due to RNG and that some stat other than magic affects it (all of my stats were higher on the level 102 Noctis). However, it's very unlikely and even if true, the gains seem to be minimal.
Conclusion: More tests would be great, but based on this data, I'd say Alterna is pure RNG with no scaling with any stats. At least not with magic.
Patch 1.07 changes:
