Charm (Ability)

Charm (おまじない, Omajinai^?, lit. "Good luck charm") is a recurring battle ability in the the Breath of Fire series.

Breath of Fire III[]

Charm costs 0 AP to use. It can be acquired after gaining 2 levels with a character having Meryleep as a master. When used in combat on an enemy, their Drop level will be increased by 1, while their Steal level will increase by 2 (these levels are indicated by an * in the tables below). Its effect on drop/steal rates does not stack, it can only be used once per enemy.

Drop Rate[]

LV*	Drop Rate
0	0 (impossible)
1	1/256
2	1/128
3	1/64
4	1/32
5	1/8
6	1/2
7	1/1 (guaranteed)

Steal Rate[]

**Steal Mod**
Agility Mod	Steal Mod
`>= 49`	12
`< 49 & >= 29`	11
`< 29 & >= 19`	10
`< 19 & >= 9`	9
`< 9 & >=-10`	8
`<-10 & >=-20`	7
`<-20 & >=-30`	6
`<-30 & >=-50`	5
`<-50`	4

**Steal Rates**
LV	Steal Rate	Drop Rate
0	0 (impossible)	0 (impossible)
1	1	1/256
2	3	1/128
3	6	1/64
4	12	1/32
5	16	1/8
6	32	1/2
7	32	1/1 (guaranteed)

The success rate for stealing is calculated with the following formula:

Success rate = Steal Mod * Steal Rate / 256

If the Item was not stolen, this item can be dropped with the provided Drop rate, which is equal to the rate for exclusivly dropped items.

For Example: Mist Man's Seeking Sword has a Steal Level of 3, giving it a steal rate of 6. Using Charm raises the Level to 5, giving it a steal rate of 16 (the chance to get the Sword nearly tripled). And if it is not stolen, there still is a 1/8 chance of it being dropped.

Breath of Fire IV[]

Charm costs 0 AP to use. It can be acquired from Marlok after acquiring a Copper Ball or better.

These mechanics determine the sucess of stealing items from the target.

If (Agility Difference < -30) Agility Mod = 0
Else If (Agility Difference < 41) Agility Mod = [(AgilityDifference + 40) / 10]
Else Agility Mod = 8

Combo Mod = ComboLevel * 2
Steal Chance = (Combo Mod + convert{Agility Mod}) * convert{Steal Mod}

If (Steal Chance >= rnd{0, 4095}) item is stolen

Combo Level can be either 0, 1 or 2
Agility Difference = "Attacker" - Target

The best chance to steal something comes from having at least 40 more Agility than the target and using Steal/Pilfer as the last attack in a Treasure-type combo, which also uses Charm. If the enemy has a Steal Mod of 1, the chances to steal the item are 1,587% under these circumstances. The probability to get a drop of rarity 1 is 1,953% with Charm.
