[General] Is there a way in game to increase/decrease base attack ?

[goldviper]

i mean i want to in increase/decrease WHITE att damage in game .
I want to change the att alot so i dont wanna use Tome (like +X att then -Y att with +/-1att Tome will have to use alot of tome) .
I use upgrade but upgrade cannot decrease LeveL and use upgrade with -X value is not smart way ,i think.
I still use stat STR/AGI/INT so it shouldnt invole to this
i just want increase/decrease base att because it effect illusion and some aura increase them (i believe non-stat green att is not )
ps: my english is not good ,sorry if you dont understand.

There is a trigger what modifies hero attribute.

There is an upgrade which increases attack speed without changing text color, but to decrease it's impossible i think.

If you want to be able to increase/decrease arbitrarily then upgrades won't work and tue only way to do it is with tomes. Instead of +/- 1 you can use a group of tomes that each give successive powers of 2: 1,2,4,8,16,32,64, etc. and then modifying the damage will take way less tomes.

Tomes also create a memory leak when used and need to be manually removed after being given to a unit. Or at least that is what I understand; someone may correct me here on the method, but they definitely do cause a memory leak.
