[quote] ... Also Luka himself was highly compatible with Monsters and Spirits, able to utilise the four spirits without any side effects at all (in comparison, Lazarus was able to use minor fire spirits, but was killed by trying to use Salamander alone for an extended amount of time). Considering it's his son, it's not unsurprising that he retained compatability with Monster magic. [/quote]

Actually Salamander explained the reason Lazarus was killed is because he didn't have a contract with them, he simply had the power infused into him. Remember Heinrich was 100% Human and was able to use them just fine. It took him a lot longer then Luka to figure out how to use their power but still.
