Maintaining enchantments?

i am a lvl 16 Mo/W and been doing stuff with my heros..mainly Ogden and i cant get enchantments to stay on me..for example mending if ogden casts it on me it shows nothing. Is that because i aint a lvl 20 yet or wouold be a glitch/bug?

You need to disable maintained enchantments such as mending by Shift +clicking on the skill in your heroes skill bar.
Then you must force the hero to cast the enchantment by clicking on it in their bar.
the enchantment will now remain on until removed, stripped, shattered, dismissed , or the hero can no longer maintain it due to lack of energy.

No. you have to disable the skill and cast it yourself on you.... Just shift click the skill. Then click on yourself and click on the enchant on your heroes bar....he will then keep the enchant up until you take it off.

heroes immediate cancel most maintained enchants unless you disable them. The solution is to disable them and cast them manually.

Ironically enough though, the warrior heroes have no trouble maintaining mending on themselves...
