Question on upgrading skills

[shaunvis]

How exactly does upgrading a skill work? Is it cumulative, or no?

Meaning say Barrage (Soldier Eddie) hits for 100.
- Level 2 Damage +5% = 105
- Level 3 Damage +10% = 115.5
(actually, level 4 is missing!)
- Level 5 Damage +15% = 132.8
- Level 6 Damage +20% = 159.4

Or is it not cumulative and goes by the base?
- Level 2 Damage +5% = 105
- Level 3 Damage +10% = 110

- Level 5 Damage +15% = 115
- Level 6 Damage +20% = 120

It's multiplicative, I believe. It is a continuous stacking so the total increase is cumulative.

Funny thing is my Barrage IS level 4.

Cool. Since I can't find 4 more freaking 3* evo shards, I'm just working on maxing him out and was hoping that was the case

Knowing how other things in this game work (hello Talisman boosts)
It's probably more like:
Base - 100
Level 2 (+5%) - 105
Level 3 (+10%) - 115
Level 4 (+10%) - 125 (for example)
Level 5 (+15%) - 140
Level 6 (+20%) - 160

In other words, the percentages stack (5, 15, 25, 40, 60) but are always based off of the base stat, not additive.

*edit* Tested and confirmed.

Magus Allied Soldier Level 5 Fearless - 4324/4714 vs 5* 80 Warrior Hell Dice/Warrior Soulless Demon
Magus Allied Soldier Level 6 Fearless - 5228/5700 vs 5* 80 Warrior Hell Dice/Warrior Soulless Demon

Unit level and Talisman level/selection the same between the two. No buffs or debuffs. Only thing that changed was Skill up.
Difference is +20%, which is exactly what the Skill up provides.

Cool thanks for testing and confirming that.
