Testing Stacking Equip & Spirit Boughs % Effects

[Hanakotoba]

1.Gold Rake [30%] = 1774 Amber
2.Gold Rake + Enamel Hunter's Garment [50%] =1794 Amber
3.Gold Rake + (Tycoon) [60%] = 1922 -1933 Amber
4.Gold Rake + Hat (Tycoon) [60%] = 1922 Amber
5.Gold Rake + Enamel + Hat (Tycoon) [80%] = 1911- 1922 Amber
6.Gold Rake + (Tycoon) +Enamel [80%] = 1922 Amber

so lowered % doesn't stack with higher one but equal % stacked?
i wonder about [Enemy drop 1.2 & 1.3 more materials], is it stack or not..
also Temporarily enhances damage dealt by 10% or 15%, i try both 10% & 15% and i think in the end gives same results?

if someone can gives more explanation about stacked % and 1.2 , i really appreciate it

It looks more like innate equipment effects don't stack with each other (rake + enamel) but spirit boughs do stack with innate equipment effects (tycoon + any gear). Try checking enamel + tycoon.

Enamel = 1646 Amber
Enamel + Tycoon = 1784-94 Amber
its like Gold Rake + Enamel

Very strange way of doing it. Where are you testing this, I'd like to look at it myself and see if the same thing happens with enamel+.

Simply go to any room with a small enemy group which you are sure you can kill in one hit with an AoE like thundering magnitude and you will absorb all ambers at same time.

Well I'd like to compare numbers to the op.

i do it at Nocturnal Hollow
note: i using Enamel w/o +

[phenir]

Hmm yeah I get the same numbers with Enamel+. I want to say it's just Enamel being buggy but testing drop rates or temporary damage buffs is difficult. The game has a huge damage range obfuscating results. Hopefully we can get some official word on it.

[Hanakotoba]

i agree with drop and temporarily enhance, thanks for the answer and test too Phenir. i really appreciate it.

The dev made a tweet about this exact subject recently. The example he gave was using the rake + tycoon; instead of increasing from 30% to 60%, it increases from skill level 3 (30%) to skill level 4 (40%). Further it seems to be a system that is similar to the buffs you get from food.
Indeed if you pay attention to the way food buff stacks, then this makes sense.

Take for example Cooked brown rice:
One cooked brown rice = natural healing 2 and overstuffed 2
two cooked brown rice = natural healing 3 and overstuffed 3
three cooked brown rice = natural healing 3...
and 4 cooked brown rice = natural healing 4.

Similarly if you put two brown rice porridge (natural healing 1) and one cooked brown rice (natural healing 2) you end up with Natural healing 3. You can think of it as each skill level having an assigned value that must be reached by each similar skill equipped to upgrade.

Using the above example:
Assume that natural healing 1 gives 100 "value
natural healing 2 needs 200
natural healing 3 needs 400
and natural healing 4 needs 800.

So you need four natural healing 2 to get the 800 points needed for natural healing 4. Or you can substitute a natural healing 3 for 400 points and get the remaining 400 for 4 with just two natural healing 2. Or you could use eight natural healing 1 if you could fit that much in the dinner menu.
Unfortunately, the effects on spirit boughs merely state their actual effects and not their skill levels and so it is unclear if there are levels in between the ones we have. There is also no skill effect summary like with the meals.
Investigating further, using the meal buff system, it seems the maximum skill level is 8. Stacking 4 renowned water (fire resist 6 upgraded to 8) gives 100% damage reduction from fire.
So it all does stack but only at specific breakpoints so it's not worth stacking lower level effects with higher level effects unless you have several of the lower. And even then it still might not be worth it if the lower level effects are much more lower level.

Back to using the example of the OP, if you could get three more 20% increases from somewhere then Enamel hunter(20%) + tycoon(30%) + rake(30%) + those items(20% + 20%+ 20%) would give you 50% (assumed value of level 5):
rake + tycoon = 40%
two 20% = 30%
another two 20% = 30%

The two above 30% combine to make 40% and then combine with the first 40% for 50%.
So in conclusion, don't stack effects unless they are the same magnitude.
