I think energy drain is one of the most useful spell. It just similar to Shavarath quests, but the mobs are even higher in CR and we need to drain them for more times *if* we definitely need to land a spell. (that i don't suggest) And if the spell is failed to land, it will still help the melees to beat the mob down. I tend to use those "mass" spells like mass hold monster/charm/suggestion and web. By probability, the spell will land on certain % of targets.
