[Spell] Morphing and Abilities?

[Faestus]

I know if a unit is morphing, it will not retain the previous abilities, so they will be lost upon transformation if added via trigger.

I know that some heroes retain their learned hero abilities.

What I don't know is: Do morphing heroes who learned/gained abilities they don't usually have (for instance I give a Tinker a Holy Light Ability) still get them after transforming into another hero (for instance, via Robo Goblin)?

If both forms have the ability by default, then yes.
Else no.

However, you can force an ability to stay on the hero by making it permanent.

call UnitMakeAbilityPermanent(unit,boolean permanent?,ability id)

you can make an ability permanent using UnitMakeAbilityPermanent(unit, permamency, abilityId)
