Hiding Passive Ability

I stink at using the search button (nothing good comes up usually), so my apologies if someone already answered this question.

Basically, I want a hero to have a spell, like say, evasion, but the hero doesn't know he has it because of a spellbook trigger. I heard something before about add a spell to spellbook, add spellbook to hero and then remove it or something, but I can't find it now

Could someone help me please? Thanks!

I've really never played around with that system, but I believe it's adding a spellbook that has a spell and then disabling it.
It's supposed to work with stuff like mana shield too (Simulating passive mana shields, etc).

Edit - eh, I'm too slow when watching TV and posting!
You're close, very very close.

Try searching with: hiding passive abilities spellbook.

That search should get you what you need ... but in case it doesn't check here:

Hidden information: Add spell to spellbook, add spellbook to hero, disable spellbook for player.

btw spellbook is under Item Abilities...

Thanks everyone, oh and to Jacek's sig: I'm new, to add rep do you click the box under the person's avatar with the checkmark and X?

I think so... the one next to the rep (or just before the rep). I don't know because I am using Pandaren skin and I see FEED button there :D just make sure you won't report me to moderators by accident...

Will do

Gave rep.
