Ok, I just turned 39. I seem to have ran out of quests, got the hunting log to rank 4. Can't do anymore until I'm 40. I guess its time to do Titan. This fight is what made me stop the last time, lol. Any tips?
Titan NM is the first real boss that makes you pay attention to dodging. My first piece of advice is to pull your camera out all the way so you can see as much of the arena as possible. Pay attention to what Titan is doing and try to not develop tunnel vision on your own attacking. As a whole, try to keep close to Titan, but keep spread out from your other allies. Titan's attacks that a DPS needs to worry about:
1) Geocrush: When Titan jumps into the air, get as close to the red edge as you can without stepping in the red. It does more damage the closer you are to the center. Try to stay close to the healer so you can be healed afterwards.
2) Landslide: The line attack that can knock you off the edge. If you stay close to Titan, you might be able to stay on the platform even if you are hit on NM. You should try to dodge it though.
3) Granite Gaols: If someone is trapped by the Gaol, attack it to free them ASAP.
4) Weight of the Land: The circle AoEs. This is why you should spread out. When they appear, just move out of them. Easier said than done, I know.
The dodging isn't complicated in an absolute sense, but it is really punishing compared to what previous bosses in the game throw at you. Don't worry, you'll get the hang of it, it just might take a couple wipes if things go badly. Even compared to other Primals, Titan can be really hard on people with lag. As such, improving your internet connection to reduce lag might help.
