Hi. This solution will go into how to beat Oryx on hard mode. This is easily one of hardest things to do in TTK. let's get into some requirements you need to meet before you even attempt to beat him:
1. Be at least 311 Light. If you are below 311 Light, you will be dealing less damage from normal. Have your teammates also be over 311 Light.
2. Have the right setup. You definitely need a Defender Titan with Blessing of Light, and a Nightstalker Hunter. A mix of Titans and Hunters works best for Oryx, although Warlocks can be just as effective (always run Self-Revive warlock if you are a Warlock)
3. HAVE THE TOUCH OF MALICE!!!!! THIS IS EXTREMELY IMPORTANT!!! Try to have all of your teammates have it, but 4 or 5 should suffice. It is a scout rifle that has the perk where you regenerate your last round, and it does double damage, but at the cost of your health (you have the immortality bubble to counter the health loss). The Touch of Malice is tied to this achievement:
Now, for the strategy. There aren't much differences from doing it on Normal, but there are a couple. I will go over the encounter step-by-step. Here is what you do:
Knights on plates/Thrall: Nothing really changes here, but you do need to generate orbs for the Defender Titan. If a Nightstalker Hunter has their super, they lure all of the thrall to the center. When they are all grouped up, they fire their Tether shot and generate orbs (this works much like the Hard Crota strategy, where you generate orbs on the Hallowed Knights)
Relic Runner/Plates: No changes
Ogres: It is largely normal, but with one major difference. After killing an Ogre, a Light-Eater Knight spawns. If you don't kill this Knight, it will 'eat' the Blight that the Ogre leaves behind. It spawns the opposite of your plate (i.e. if you kill the back left Ogre, the Knight that will eat that blight spawns at the back right plate) There are three different strategies you can do. They are:
1.
Normal strategy: This is like doing it on Normal, except you just kill the Knights as well. This is the strategy you will probably complete the raid on.
2.
No-Knight strategy: This is where instead of killing the Ogres straight away, you get them down to low health, Once the runner gets the relic and slams, everybody goes up to the Daughters platform, then staggers Oryx. Once he is staggered, you kill the Ogres, then rapidly detonate the Blights. The point of this strategy is to prevent the Knights from spawning. This is an extremely hard strategy to pull off, and I would not recommend doing it.
3.
Challenge strategy: This is the strategy you use if you do the challenge mode for Oryx. You kill the Ogres and Knights straight away but instead of detonating the Blights straight away, you wait until there are 4 blights beside each plate, then you detonate them at the same time. This brings Oryx's health from 100-0 in one go. This strategy is actually pretty easy, and this is how I got the raid done myself.
Ad (enemy) control/Helping with Ogres: You have the Titan Bubble (with one other guy) go up to one of the Daughter's Platforms (the one opposite of Oryx). The Titan pops his Bubble, and they use their Touch of Malice to help kill the Ogres and the Knights. This is what the Titan Bubble is needed for. Try to generate enough orbs to supply the Titan with at least 4 Bubbles (you do this by activating your Supers on the ads after the Blights are detonated/Oryx is staggered).
Bombs/Shade: Nothing changes but I do need to note that if you use the Challenge strategy, instead of 2 bomb runs and 2 Shades, all 4 rounds will be the Shade.
Final Stand:Nothing changes
If you have followed all of the suggestions, then congratulations, you have beat Oryx on hard!
