An explanation of the elemental scale (since the new elemental debuff comes soon)

So this thread got me to make a post on its own, explaining how the elemental "scale" works. First a little trip into the battle.js: picture. As you can see there's a scale in the game, that ranges from absorb -10, to weak 20.

From -10 to -1 is absorb. 0 is null. 1 to 9 is resist. 10 is neutral. 11 to 20 is weakness.

A few examples:
So -10 would be 100% of the damage absorbed, -3 would be 30% of the damage absorbed, 0 would be nulled, 3 would be 30% damage, 9 would be 90% damage. 10 means 100% damage. 12 would mean 120% damage. 17 would mean 170% damage. 20 would mean 200% damage.

Now most of these won't really get used, so here's the ones that count:

-10 is standard absorb (100% dmg absorbed). 0 is null (0% dmg). 5 is standard resist (50% dmg). 10 is neutral to the element (100% dmg). And 20 is standard weakness (200% dmg).

So here's why you should care. With the arrival of the new status effect on the Basch1 banner, we can influence the elemental scale of the enemy. The effect (i'll use Imperil, like u/Sandslice decided to call it here) essentially lowers the elemental resistance by -2. Which means +2 on the scale.

So, if an enemy is neutral, you do 120% damamge (you're on 10+2 now). Since you go into the territory of weak, that also means it counts as weakness in the game for the sake of RM like Attunement or the bonus SB gain from hitting weakness.
If an enemy is already weak, it won't have any effect, since as you can see, it can't go over 200% damage (20 on the scale).
But if an enemy absorbs the element (-10 on the scale) you'll move to -8, which means only 80% of the element would be absorbed.
If the enemy nulls the element, you'll do 20% dmg after using Imperil (2 on the scale).
And if he resists it (5 on the scale), you'll move to 7, meaning you do 70% damage with the element.

I hope i got everything right and it doesn't look too confusing... Feel free to ask any questions and i'll try to answer them (no promises though).

It's also important to note, that the elemental resistance (20% dmg reduced) from attach element (also known as En-X) works different. It doesn't move the scale and it is not a reversed Imperil. As such it will stack multiplicative, not additive with elemental resist equipment (which does move the scale). Credits for this section go to u/Elninofr.
