Today I want to talk about buffs and debuffs.
What are buffs and debuffs?
A buff is something that strengths your OWN team, as example increase attack, increase speed etc. A debuff is something that weakens your opponents team, as example decrease attack, decrease defense, decrease speed but also DoT effects can be counted as debuff.
What type of type of buffs and debuffs exist?
There are 2 types of buffs and debuffs. Active buff/debuff and passive buff/debuff. An active buff is something that is left on the ninja after you use a skill. As example in my screenshot above you see multiple Icons, those are active buffs and debuffs. A passive buff/debuff is not directly visible but hinted by the ring under ninja like Indra Sasuke, Kushina, Ashura Naruto and co.
How do they Interact?
Active buffs/debuffs do not stack with anything that has the same Icon and are replaced the with the last buff/debuff of the same type. As example if you use Reanimated Nagato to increase the attack of your protagonist by 30% but also use Susanoo Kakashi you will replace the 30% with the 15% from Susanoo Kakashi and vice versa. However they still do stack with passive buffs/debuffs. As example Re Nagato increases your teams attack by 30% but you also have Toneri in formation which increases your supports attack by 20%. This means you will have an increase of 56% attack.
Passive buffs/debuffs do stack with the same type. This means you could use Indra Sasuke 15% attack decrease with Chakra Goddess Kaguya 30% attack decrease and get a total of 40.50% attack decrease as long both of them are alive on the field.
The formular to stack debuffs is ((1-30%)*(1-15%)) = -0.4050 = 40.50% decrease
The formular to stack buffs is =((1+30%)*(1+20%)) = 0.5600 = 56% increase
How long do they last?
Active buffs/debuffs last a specific amount of turns, a turn is over after the ninja has attacked. As example Re Nagato attacks and buffs 30% attack on my team for one turn, my protagonist attacks right after because he attacked my protagonist looses the 30% attack buff.
Passive buffs/debuffs are always active AS LONG the ninja in battle is alive. If your Indra Sasuke dies after the first hit you will lose your -15% attack decrease.
Thanks to Ghostie McGhosterson pointing out that debuffs have diminishing returns while buffs have compounding gains.
