I saw some city type interlocking tiles somewhere on here that you might want to check out that would work really well with Assassin's Creed themed quests.
Use these quest ideas if you like:

The assassin could make the jump automatically. You wouldn't even need to make the human enemies as under the influence of a spell, they should be standard enemies along with spearman and archers as well as templars, clerics, priests etc.
I really had to hold back with the assassin. I wanted to incorporate more from Assassin's Creed but he/she (haven't decided yet) would basically be a god. I think the one I've got might be a bit over powered. I'll probably take away the leather armour as starting equipment. Also the death strike skill makes it harder o get a instant killing blow (but harder to defend against) with more attack dice, which was the idea, but it also makes it harder to get a death strike from behind and it really shouldn't be I'll have to sort that out.
