Tome that permanently increases the movement speed

[MN Lahmar]

Hello guys, i'm making a tome that permanently increases the movement speed of the hero when consumed.

• Tome of Haste
  • Events
    • Unit - A unit Acquires an item
  • Conditions
    • (Item-type of (Item being manipulated)) Equal to Tome of Haste
  • Actions
    • Unit - Set (Triggering unit) movement speed to ((Current movement speed of (Triggering unit)) + 20.00)

I'm not sure if this trigger is 100% correct. I mean if the triggering unit is a buff or aura effect that increases his movement speed will that affect on (Current movement speed of (Triggering unit))?
For example, we take a paladin with 270 base speed and we cast bloodlust on him. Let's say his movement speed with the effect of bloodlust becomes 300. At that moment he consumes a tome of speed that will increase permanently his current speed with 20. Will it be 270+20 or 300+20 after the effect of bloodlust ends?

If there's an easier way to do this pls tell me.
Thank you.

You can simply debug it with game messages to check if it's correct.

You have to test this i guess.
Last i checked movement speed alterations did not stack up without workarounds.

You can give them a hidden ability based off of the boots of speed. To make it stack, give it levels and increment the level if it already has the ability.
This will also allow it to persist through morphs (provided you make the ability permanent).

I've tested it. Does not work. The buff that increases speed will mess up everything.
Damn i'll use only 1 tome and instead of ((Current movement speed of (Triggering unit)) + 20.00) i'll use this ((Base movement speed of (Triggering unit)) + 20.00).
Not worth the trouble.

you may want to try this library
Movement Modifier
to give permanent move speed bonus use
call UnitAddMoveSpeedBonus(yourUnit, 0.00, 40.00, 0.00)
where last "0.00" means permanent (its also possible to write how many seconds bonus will be active), 1st value (0.00) is percentage bonus, 2nd value is flat bonus (like from boots of speed item). So this will boost permanently speed by 40
