Wondering about a few rune magic spells

[camelotcrusade]

I'm interested in hearing your strategies for a couple spells I haven't used or scribed yet.

Justice - It's rune magic and it says it gathers X runes (or X adrenaline) from all your troops and then redistributes them eveningly among all your troops. At level 1, X is 2 runes or 10 adrenaline. Is it supposed to be for long fights when you run out of runes/adrenaline?

Timelessness - adds extra rounds to the duration of spells currently on you, limited to low level spells and only 2 rounds at first, eventually up to level 4 spells for 4 rounds. I guess you cast timelessness when it's cheaper than maintaining the buff(s) individually, right?

Negation - All spell effects on the target are reduced to 1 round. Like timelessness it starts at low levels with a low duration, eventually affeting lvel 4 spells for up to 4 rounds. I'm drawing a blank. Someone suggested using it with kamikaze but then another person said it doesn't work with it. Is it like a poor man's cure you forget about, knowing whatever happens to that unit for the next few rounds it will wear off soon? I'd still rather dispel it, I think.
