======================================================
Just showing how insanely easy Geiseric can be if tackled after beating Barthandelus 2.
Zantetsuken will instant KO if the enemy's HP is lower than:
Odin's PA * 3 * Chain^2
(PA = physical attack stat)
======================================================
=Notes=
The Eidolons' Level is dependent on the Crystarium Stage unlocked and the number of Level 5 Roles the characters have. Since there are 10 Crystarium Stages and 6 Roles to master, the max level an Eidolon can reach is 16. At Chapter 11, Crystarium Stage 8 is unlocked, so each Eidolon is at Level 8. Once Barty 2 is beaten and the Crystarium expands, their level becomes Level 9.
In Odin's case, his Physical Attack stat at Level 8 is 649. Then at Level 9, it makes a huge jump to 2283. Using the Zantetsuken calculation, the max remaining HP that Odin can inflict instant death on is:
(2283)(3)(9.99)^2 = 683,530 HP
Now, checking Geiseric's stats, we see that his starting HP is 702,000, so we only need to chip off a bit of HP, raise the Chain Gauge enough, and poof, battle is done! No leveling and only little prep needed.
For this battle, I aimed to raise the Chain to at least 800%, so I had to lower Geiseric's HP to:
(2283)(3)(8)^2 = 438,336 (~60% HP)
