How to make heroes maitain enchantments on you

I know it's a noobish question, but when i click on ogden, then on my name and make him cast enchantments, he just casts them and then immediately after they go away, is there any way to make him hold the enchantments on me? Thanks in advance

hold shift+click the skill... you will notice it has a cross over the skill.... then just click the skill and the hero will cast it and maintain it.

thanks a lot!

To clarify, hero AI does not like any maintained enchantments, as it interferes with their energy management coding. To use them, disable the skill(shift+click) on their skill bars so that the hero will act as if the skill is not on their bars and manually cast them on yourself.
