I didn't see any topic on this already, so I just wanted to bring this up: It doesn't look like kills by summoned objects (the leech, at least) count toward Lona's kill count. At the very least, when doing the graveyard's kill 20 undead quest, I ended up practically clearing the whole graveyard via leeches without triggering quest completion (works fine doing standard damage spells or via companions).

Not sure if this is intentional?
