Damage absorbtion stacking?

Hi, hows % dmg absorb stack example soldier lvl50 exclusive skill/possession + maiven sphere + item? (Add or multiply or combo?)
Also, anyone notice weird maiven sphere scaling beyond max lvl?

I would say it is multiplicative.

The scaling is not weird, the damage penalty applied on you diminishes as the skill is leveled.

This was initially confusing to me as well, but now I can explain Maiven’s Sphere

Let’s look at level 12 of the skill

20% Damage Absorption - you take 20% less damage from enemies

Total Damage modified by -8% - you do 8% less damage to enemies (NOT total damage you take, as I initially assumed)

7% Physical Damage Reduction - you do 7% less Physical damage to enemies (NOT reduction in physical damage you take, as I initially assumed)

The last two are drawbacks of using Maiven’s Sphere. The more you level the skill past 1, the higher the drawbacks. The drawback’s less damage is multiplicative, not additive of the damage bonus so it is a big deal. I.e. your total damage is multiplied by 0.92 for the 8% penalty, extra penalty for physical damage.

If you get the skill higher than level 12, the drawbacks are lessened.

Also, the order of defenses is:

Fumble, Dodge and Projectile Deflection
Chance to hit via Offensive Ability vs. Defensive Ability
Shield
% Reduced Damage from Monster Types
Armor
Resistances
Reduced Damage from Monster Types
% Damage Absorption
Damage Absorption

That means Maiven’s Sphere isn’t that great in reducing physical damage, as it is factored after Armor. Some players max it, some leave it at level 1 for lower damage penalty.
I still like to max it for Ultimate though, as enemies hit so damn hard.

It is multiplicative,Scalling is not weird.
