Mechanics vs. Natural State Since most of you are raiding and LFG, I will post info here on advanced game play like Mechanics. First you must know what the difference is between a Natural state and Mechanic. Do note that both natural and mechanic are able to kill you. Natural State is what it's purpose is. Example: the chaos thralls. These guys are supposed to get close and blow up. That is their natural state, just the same as most mobs are supposed to shoot at you. Mechanic is a extra event or trigger that adds a challenge to a fight or travel. Few Examples: Hydras explode and do damage when they die. This is not how they kill their target. They kill naturally with their weapon system, when they die they give off a burst of energy that does damage. Example2: During a boss fight mobs are summoned into the fight. Think of Shield Brothers, after a set time or after their health reaches a certain point monsters are summoned. This is not how the Brothers kill you, but it still can kill you. Another example would be the Fight with Oryx. When he is below 25% he warps you an area where he hides in the shadows. The mechanic is he hides until a timer goes off and then he attacks. I'll rub it in more. Lets look at a boss. Disclaimer; I only know what I have seen on video, at this point I have not fought in Crota's End. Take Crota in the six man raid. Naturally he must shoot you with his bolts or smash you with his sword. This is how Crota kills his targets. Mechaniclly he summons more adds/mobs, ignites the darkness behind his center post, and also causes a debuff to stick to player. These are mechanics that can still kill you. On the flip side of that he has a mechanic that protects him. We can damage him with our weapons (our natural method), until his shields are gone. At this point he falls to his knee and now he is immune to our weapons. We must get an outside source, a sword from a Knight, and use it on him to lower his health. Without that sword mechanic we cannot kill Crota. This adds the challenge. Understanding Mechanics and how the AI naturally tries to kill you helps you avoid and win the fight. Most common seen in most gaming; Timers, Enrage, Debuffs, Mass AoE, knock backs, party separation, and added mobs. To name a few.
