Killia's Evility "Bolster Spirit"

[Capability]

Has anyone found any situation where this evility (which is for some reason put on the main character of the story) is even remotely useful?

For those that can't recall what it does: "Increase Revenge Gauge gain of ally units on the map by 1%". Fighting Instinct, a common warrior evility that costs 1 less gives 50% Revenge Gauge gain (but only for the unit itself). Also these evilities don't seem to affect Revenge Booster/Swift Strategy/Tension Booster.

Genuinely curious if someone managed to pull of something sweet with some combination of Bolster Spirit and other evilities or skills. Just so hard to imagine one of the evilities of the main character seems so unusable.

apperently it's an addictive 1% to normal (non-evility) revenge gains, which is basically a 20ish percent boost overall

Just as many of the evilities, this one serves no purpose whatsoever. Unconditional Love is a flat 30% increase to attack power with the clause that you gain no HL upon killing stuff... Except you can sell items to gain them. And it has a cost of 2. Pick evilities like that over revenge-boosting skills, and stick to tension booster.

There are a lot of pointless ones, just saying. Look up best builds and dont forget to look at your DLC characters for transferable ones.

Assuming this is a common evility, 2 things to note.

1. Common(most) evilities can be transfered to scroll via chara world.
2. Assuming this stacks then you could have 10 support characters with it to give all your units a 10% increase.
Bonus: This doesn't have to be on the character that already has revenge booster (or what ever the 50% increase evility was called) so it could be stacked on top since the other one effects all your characters.

These are just my observations, but don't underestimate how usefull support units like that can be.
