Using Archane Echo with heroes

I made a curses necro hero and want him to spam Spiteful Spirit using Arcane Echo.

The trick he seens to think all other skills are better candidates for be echo-ed then Spiteful Spirit. Anyone know a trick to force him to use Echo+Spiteful?

Micromanage it. aka cast arcane echo then SS on the first target yourself. There really isn't a better way. Some people say to put it at the beginning of your bar, that doesn't always work.

toggle all his other skills off.

shift+click on skill

Aside from disabling Arcane Echo and manually echoing the spell you want, there is no way to do that. Don't give your heroes Arcane Echo if you don't want to micro-manage their bar. They do it wrong. I tried the same thing once; the hero echoed Enfeebling Blood.

I think this can work if I use Arcane Echo and only contigence spells (like Taste of Death).

Still, he can mess up now and then.

I gave up. I use Arcane Echo all the time with my Fire Ele and Savannah Heat, but I won't give it to my heroes. I caught Sousuke one too many times Echoing Fire Attunement.

I gave up on using Echoes on Heroes as well. They're just pathetic at using it correctly.

My Master of Whispers thought it was a good idea to echo Parasitic Bond. Considering he had Insidious Parasite and Spiteful Spirit, he used the only spell with a fast recharge...........

Micro manage, or don't use it on heroes.
