ToME: the Tales of Maj'Eyal

When using the Mirror of Reflection to disable the visual effects of sustains, if you have Hymn Adept and disable the effect for your currently active hymn, it will give the bonus for deactivating the hymn without actually deactivating it, and you can keep doing this every turn.

So I'm playing a necromancer with both aura of undeath and through the crowd. When I have both active, aura of undeath doesn't seem to be applying its effect to my minions. Actually, it may also affect commander of the dead? It's difficult for me to verify due to the random chance involved, but I do...

I own the steam version of the game and bought both DLC on there. Is there some way to enable that DLC on the standalone version?
