The Attribute / Abilities System

Both systems use a different scale but the weakest 'Human' in d20 is 3 and strongest is 18 on a bell shaped curve (approximatly). Bushido uses a linear range from 1 to 40 but because it uses a fixed point system it produces the same result for orinary people.

If we multiply the d20 values by 2 we get to the Bushido range. IE d20 Strength 16 become Bushido Strength 32 or BCS 10 this make the transformation simple.

Bushido_Attribute_BCS := Bushido_Attribute_Score / 3

d20 Ability Mod := ( d20_Ability_Score - 10 ) / 2

Bushido_Attribute_Score := d20_Ability_Score x 2:

d20_Ability_Score := Bushido_Attribute_Score / 2

From d20 to Bushido

Hence the Creature:

d20 Ability Values: Str 19, Dex 15, Con 10, Int -, Wis 10, Cha 2

becomes

Bushido Attribute Score: Str 39, Dex 30, Con 20, Int 0, Wis 20, Cha 4

But the attributes are different as well:

• Strength is simple, Str = Str.
• Bushido Health becomes Con.
• In d20 Wis is the intuit attribute not Int but Int it is also used for knowledges so lets say Wit = (Wis+Int)/2.
• In Bushido Will is Wis and Cha so lets do the same average them Wil = (Wiz+Cha)/2
• Bushido Defness is closed to d20 Dex and is used in both system for initiative order.
• Speed is a problem as in d20 your move is a function of your creature type, weight and your number of attacks is a function of your class and level. Lets use a Bushido system for this rather than a d20 one, hence we will use the creatures move alone. BAP = Speed / 3 ft/rnd. Move = ft/rnd. The average Bushido Human BAP is 3 (guess) in d20 this would be 30 (I think). Move = 30 ft = 10xBAP = 10x (Speed/3) Hence Speed = Move * 3 / 10. If we simplify it and say divide by three.

Bushido_Str = d20_Str * 2

Bushido_Dft = d20_Dex * 2

Bushido_Spd = d20_Move/3

Bushido_Hlh = d20_Con * 2

Bushido_Wit = d20_Wis + d20_Int

Bushido_Wil = d20_Wis + d20_Cha

Hence:

d20: Str 19, Dex 15, Con 10, Int -, Wis 10, Cha 2, Move 40ft

become

Bushido: Str 39/13, Dft 30/10, Spd 13/4, Hlh 20/6, Wit 10/3, Will 12/4

BAP 15, MNA 1, ZAN (55)
