One should take extreme caution when approaching Qwilkhan. The parent can control itself and not poison those it trusts, but the child lacks control of its toxins; any touch of its spines will be painfully poisonous.
If you come across a young Qwilkhan playing by itself, never try to catch it. A Qwilkhan uses the pressure of water it swallows to shoot toxic quills all at once from all over its body.
