How do Skills stack in Formation (Decrease Enemy Defense)

Howdy all,

Been playing the game for about a month now and really enjoying it.

I have 4 creatures in my formation (All 4 have Decrease Enemy defense) and had questions about how they are applied in combat.

My assumption:
Enemy player has 10,000 Defense.

I have 4 creatures each who decrease enemy defense by 10%.

First will decrease 10,000 to 9,000. . . Second will decrease the 9,000 by 10% again to 8,100, Third by 10% again to 7,290. . . ect


Guess what I mean to ask is
1) Do they stack sum (10% x 5 = 50%)?
2) Stack with dimishing returns(like above)
3) Stack in some weird formula way I'm not aware of
4) Don't stack at all.


Thank you

you can only have 1 skill Type active in your team at a time ( agility/ DeD / DEA/ IPA .... etc.)
but if you level up the SKILL of your monster the affect is greater... think 25% at Skill(20) for Ded, Dea, IPA, Agility, IPD....

Same skills do not stack. The game will use the skill from the first one in your formation if you have multiples of the same.
