Some questions

[Malhorne]

Okay i got a few questions :
- Is there a way to reduce unit's armor with spellbooks ?
Because i tried with spellbook on an unit and her armor stayed the same.

- Is there a way to reduce unit's attack speed with spellbooks or with triggers ?
Never tried.

- Is there a way to disable unit's attack / spells during an amount of time without using silence spell ?

1)How did you try?You can do that with spellbooks(if item armor skills not working use an aura skill)

2)Yes

3)You want to prevent unit casting spells, but you dont want silence, good luck

1) I tried by adding item bonus armor in spellbooks and the unit (non-hero unit) never got less armor :/

2) Are you sure it works on non-hero unit ?

3) Okay XD ! I want prevent unit attacking too ^^
But if it needs a silence dummy spell i'll do.

You can disable attacks by giving the unit Cargo Hold (orc burrow) ability with 0 capacity. It won't prevent spells.

Yes you can. Although you don't really need a spellbook though. Item Armor Bonus and Item Attack Speed abilities are hidden by default. If you are interested, check out some BonusMod systems, like Custom Stat Systems in my signature.

- Is there a way to disable unit's attack / spells during an amount of time without using silence spell ?

Yes. You can set a field in the Silence spell to either disable attack/spells/both.

Another way to prevent attack is adding the Cargo Hold ability to the unit.

Oh wait I honestly don't mean to repeat Maker's answer. Yeah well it seems we both posted at the exact same minute

Ok thanks to both of you.
I knew for the silence trick but not for the Cargo hold thanks
