Best uses for Trucidation and Infusion?

[Daldaen]

I also don't see much purpose to either of these spells. As I'm leveling my necro, I haven't yet found a situation where I have room on my spell bar for such situational spells, or when I would happily throw out 500 plat or so to cast either spell.

The huge recast times just mean I am forced to hold them on my spell bar for extremely rare circumstances that warrant casting them.

Infusion I can see *some* worth on a Velious raid to continue pumping mana into cleeics at the very end of the fight... maybe. But that's an extremely expensive 3-4 Twitches.
