If you're talking about a temporary change, just apply a state that modifies the parameter.
@actor.add_state(17)
@actor.add_state(17)

@nolund: unfortunately only the str, dex, agi, int, maxhp and maxsp can be changed that way. i'm looking to use an item that calls a script to change those values.
@brewmeister: could you explain tht please?

Like Brew was saying, you could use a state like this:
If you use a state, you could use the event command or use Brew's suggested code. But this depends on your exact needs. You could also do some weapon/armor alterations to achieve the effect. Like equip a character with some armor that reduces/increases the stats (although you'd have to make it fixed to make the player unable to remove the item). If the state and armor ideas won't work, you need to give us more details on what you want like how long it'll last, whether or not it's permanent, etc.

yeah that state thing won't work. what i want to do is increase or decrease the atk/pdef/mdef stat by set numbers (+15) the same way you would the other stats(hp, sp, etc). like say if a use an item in battle that increases attack, for example.

ATK, MDEF & PDEF are not stored attributes on the character (actor) object, they are calculated values from the weapon, armor(s), & states.
You could create a new state on the fly, and apply it, calculating the correct atk_rate, pdef_rate, mdef_rate percentages based on the character's current values to produce the desired effect.
Or you could apply new attributes to the Game_Actor or Game_Battler class to store a modifier for each attribute, then change them through script commands. e.g.
$game_party.actors[0].atk_mod = -50
You would then need to modify the atk, pdef, & mdef methods of Game_Battler to add the modifier before returning a value.

so your saying there's no easy way of doing this is there? :sad:

Did I say that? <looks up> 
No, I would consider adding an attribute 'relatively' easy. It's a matter of understanding how those 3 existing attributes are derived, and finding the other methods that call them. (Cntl-Shift-F is your friend.)
In a new script above Main, below Scene_Debug...
Add the 3 new variables (attributes) to Game_Actor, and initialize them in the setup method...
Now, copy the atk, pdef & mdef methods from Game_Battler, and we'll overwrite them for the Game_Actor class only. (Not for the Game_Enemy class.)
I added the modifiers AFTER the state calculation. Also take a look at the base_atk, base_pdef & base_mdef methods in Game_Actor. Each attribute is the sum of the attribute for the weapon & armors, * the attribute factor from all active states, + the new modifier.
Get it?

OH I SEE. the _mods would be used to add values to, thus changing those attirbutes right?
Brewmeister

Yes. So each value will be calculated as it normally would, and THEN the _mod value will be added (subtracted if negative)

so can i adjust these using the call script function and if so how? just type @atk_mod = +15?

$game_party.actors[0].atk_mod = 15
0 is the first actor in the party
you don't need a '+' with a positive number
you do need a '-' for a negative number
$game_party.actors[3].pdef_mod = -50
0 is the first actor in the party
you don't need a '+' with a positive number
you do need a '-' for a negative number
$game_party.actors[3].pdef_mod = -50

ok so i'd do this four each party position, right?
if this works you are a godsend dude.

Yep, subtract 1 from the position in the party (Status Screen). The first actor is $game_party.actors[0], the 4th actor is $game_party.actors[3]

so the entire script should look like this?
if so, i get an error msg like this: line24: TypeError occured. nil can't be coerced into where did i go wrong?
Code:
class Game_Actor
attr_accessor :atk_mod
attr_accessor :pdef_mod
attr_accessor :mdef_mod
alias attr_mods_setup setup
def setup(actor_id)
attr_mods_setup(actor_id)
@atk_mod = 0
@pdef_mod = 0
@mdef_mod = 0
end
#--------------------------------------------------------------------------
# # * Get Attack Power
# #--------------------------------------------------------------------------
def atk
n = base_atk
for i in @states
n *= $data_states[i].atk_rate / 100.0
end
n += @atk_mod
return Integer(n)
end
#--------------------------------------------------------------------------
# * Get Physical Defense Power
#--------------------------------------------------------------------------
def pdef
n = base_pdef
for i in @states
n *= $data_states[i].pdef_rate / 100.0
end
n += @pdef_mod
return Integer(n)
end
#--------------------------------------------------------------------------
# * Get Magic Defense Power
#--------------------------------------------------------------------------
def mdef
n = base_mdef
for i in @states
n *= $data_states[i].mdef_rate / 100.0
end
n += @mdef_mod
return Integer(n)
end
endif so, i get an error msg like this: line24: TypeError occured. nil can't be coerced into where did i go wrong?

it happened when i tried to look at the hero's status. i hadn't even done anything else yet.

i see what the problem is. i'm using a script by leon that aadjust these stats in accordance with the Str, Int and dex stats. i opened up another project and it works fine. anyway to meld these together? i can pm it to you if you want.
