Enemy Blinking, Damage Mitigation, Extra Turn Skills

Hello Everybody, I am new in RPG Maker MV. I am planning to make my own game one day and of course, with the help from everyone, I might be able to. :)

I bought this game 2 days ago cause I want to make the game legit. Right now, I am still considering the game play first than story or design. Most of the mechanics are now okay. However, I have two questions:

1. If you have played Brave frontier or Final Fantasy Brave Exvius, on certain enemies with a very Big Sprite, they uses Blinking enemies when attacking, or to be exact enemies become negative like photos when they are attacking in action. How do I make it like that? I am planning to make the ones with Big sprite attack like that so I won't need to make much effort.

2. How does exactly the mitigation damage formula applied in the game? Example: When I use Skill damage mitigation 50% and I guard at the next turn (commonly 50% damage reduction), how do I make the formula stack multiplication, not additive?

3. The game will be Turn based RPG with based on Agi/Speed, when the player is in their turn, there comes to my mind that why don't I make a skill with extra turn but with High cost of MP? However, I don't know how the mechanics work. I also don't see many people do that. Can I know how this works?

Thank you very much. :)

In general we encourage people to have one query per thread because it can get very confusing. It also makes it harder for other people with a similar problem in the future to find the thread with the answer.

1. The easiest way is to edit the enemy sprite sheet in an image program (e.g. GIMP which is free) so that all action poses are the same with this effect
2. What exactly do you mean by "Skill damage mitigation"?
3. This will require a plugin.

===> I am sorry since this is my first post, I will make sure to make one query per thread.

1. Edit an enemy sprite in an image program, huh? I think I will do that. Do you have any tutorials provided for that?
2. Skill damage mitigation, in Brave frontier, their Brave burst or super brave burst some may have specific buffs. One of it is 50% Damage reduction. By using that Burst, you applied buff for yourself and your allies for X turns. I want to apply that in my game, however, I haven't got the slightest clue on how exactly the formula works in skill + Combined with guards on the next turn (if the mitigation damage buff is still there). Do you know how to do it?

Example: I create a skill Holy Guard => Reduces damage 50% for 3 turns.

1st turn, I use Holy Guard (Applied 50% Damage reduction)
2nd turn, I guard (With 50% damage reduction buff on + 50% damage reduction from guard, it should be 75% damage reduction total). It must be multiplication not additive.
3rd turn, Free action.
4th turn, Buffs run out.

So to sum up:
How do I create the skill formula like in the 1st turn?
How does the formula guard stack with the formula skill of Holy Guard?
How does the game know if the buffs run out in the 4th turn so that when I guard in the 4th turn, for example, it won't stack damage reduction anymore since the buffs run out?

3. A plugin? I couldn't find any plugin for that. Yanfly doesn't provide that as far as I know. Do you know one by any chance?

Thank you.

For number 3, just use Instant Cast. You want to change, a skill not an entire battle overhaul.
Battle Systems give a complete overhaul to the battle mechanics, typical changing how the battle system works. Take ATB, it adds time to a turn-based system. So that during every turn there is a wait period, then you select an action, then you wait agsin, then you do an action. It changes how a battle system works, the Default battle system aka DTB, works where everyone puts in their action, and does depend on their speed, which is a formula that uses agility.

I'm saying this to show, that what you're asking for really isn't a battle system overhaul but a single mechanic, in this case you want to make skill that doesn't use a turn.

That is something that works with all battle systems (that are not real time) as their are pauses in those systems.

@Zarsla, Oh my god, I didn't realize that. How stupid I am not to see Yanfly engine plugin first. Well, thank you for solving problem number 3. That goes for you too, Kes.

I still need to solve number 1 and number 2 which number 2 is quite number 1 priority.

Number 2 is easy, there are 2 ways to do it.

On the gaurd state remove the gaurd flag and instead go into traits, and to Param and to sp-parameter and select
physical damagae and change the numbrr to 50.
Do that again but instead of physical damage do magical damage.

Now make a holy gaurd state, in tge Temovel conditions. set Auto-removal Timing to 3, in both the little boxes.
Now in the traits box, go to params and go to sp-parameters and set Physical and Magical Damage to 50%.

Attach Holy Gaurd State to Holy Gaurd Skill,by going in the Effects tab of your Holy Gaurd Skill and going to State then Add State Holy Gaurd.

The only downgrade, is that gaurd will always reduce damage by 50% and the parameter gaurd effect is useless for the skill Gaurd.
It is still useful for the Gaurd Flag, as that's what turns on gaurding, but imo it's not good at making stacking damage with. As it's not intuitive enough.
Note that all params stack, and states will stack(unless change by a plugin), so stacking states are easy.

@Zarsia, I see. Let me try this first. I will give you an update soon. How about number 1, sir Zarsia?

Not sir, ma'am or miss.
If I understand what you want exactly is a photo-negative look when using a specfic skill.
You could try enemy transformation. And then have them transform into an enemy with the photo-negative verzion image.

However you'd still need a photo-negative enemy image, I recommended using gimp, and making a copy of your enemy image and then look for a gimp tutorial about how to get a photo-negative look for an image.

The only problem is stats and making sure that they transfer, and not reset, which I'm not a hundred percent sure on how to do that.

===> Whoops, my bad miss. It works so much. Thank you for your guidance :) Cheers
