/**
 * Dr. Chaos is a boss @ Pavel's Ruins. Some things to know :
 * <ul>
 * <li>As a mad scientist, he thinks all are spies, and for so if you stand too much longer near him you're considered as an "assassin from Black Anvil Guild".</li>
 * <li>You can chat with him, but if you try too much he will become angry.</li>
 * <li>That adaptation sends a decent cinematic made with the different social actions too.</li>
 * <li>The status of the RB is saved under GBs table, in order to retrieve the state if server restarts.</li>
 * <li>The spawn of the different NPCs (Dr. Chaos / War golem) is handled by that script aswell.</li>
 * </ul>
