Problems with Turn back time

[Metathron]

No retaliation is great, but pity you can't drain life from bosses too. But maybe that would be too much too ask for.

Maybe the rules are different in Champion of the Arena, but I was fairly certain I was draining the bosses life to revive. I might be wrong though!

If you change from vampire to bat or the other way, then turn back will not work for that turn.
You have to be either a bat or vampire from the start of the turn till casting turn back time.

Yep, I have been using Vampires in The Legend and this was a common problem.

Also, there is one more possibility - if another unit is standing in the square the unit you want to resurrect has been in the previous turn.

Then does the same problem applies for werewolf and werewolf elf (count as two different units)?
