I assume the upcoming light raid eidolon uses the same scaling, and am trying to figure out whether it's worth using her as a main instead of Barong, which is what I currently use.
Seems my question got buried. I did some research, it turns out someone on the JP wiki has the formula, so in case someone is interested, the special attack is: 10 + 40 * (1-HP / MHP)%

So it is basically a dmg increase of between 10%-50%. However, to use it, you are sacrificing another main eidolon, probably a 40%-45% event elemental eidolon if you are even considering using these. If you do not have an elemental soul weapon, the special attack is probably not worth the eidolon elemental loss. Even with a soul weapon, you need to average around 60%-ish health for special attack to come out ahead. Could be worth it if your tactic in a fight is to eat an AoE OD then FB right after - the dmg gained from bursting at low health may make up for dmg lost when near full health. If you normally burst before an OD to try to stun the boss and avoid getting hit, these special attack eidolons probably will not help you.

Note that while running the numbers, I uncovered one interesting use case, which is if you have the setup I currently have: elemental soul weapon, 100% eidolon support but do not own a 100% so you are stuck using 40%/45% as your main, assault of 117% or greater (9x SR assault weapons or better.) It turns out that if you replace one assault weapon with a vigoras weapon (one of the current raid event SR weapon is vigoras) and replace Barong with Abou as main, you have a dmg curve where you are losing only 2% dmg relative to initial setup when near 100% health, breaks even around 70% health, and has up to 20% higher dmg when near death. Basically you are sacrificing very little dmg when near full health but still reaping some noticeable gains when at low health.

I have not MLB Abou and slvl the SR vigoras weapon yet, so I can't verify the above, but can report back if there is interest.

tl;dr - Abou's special attack has its uses, most useful to those that have 100% eidolon friends but do not own one themselves AND you frequently FB after eating AoE from bosses. Useless for almost everyone else.
