Arah Midboss
For a PuG my only real advice is for you to practice to the point where you can live for ages and ages. Phase 2 is really the only difficult phase (even for a PuG) so as long as you can survive the entirety of phase 2 you’re golden.
At which point it basically becomes practice practice practice.
Unless you’re doing jotun, in which case, dont roll with a PuG.
assuming phase 2 is the only real issue:
1. Spread out
2. pay attention to where he is facing so you can guess who he is going to attack
3. always run AWAY from the boss when he uses his AoE, so you don’t get hit by the projectiles on the way to the circle
4. Watch for the green wave that appears when he phasewalks
5. He usually phasewalks the same 1-2 people.
6. If you are being phasewalked often, stay near the wall as you run around the arena.
To keep from overloading new players with too much information, don’t spend too much time explaining phases 1 and 3. All they need to know for phase 1 is to stack at max range and kill grubs. For phase 3, they just need to know to kite, and roll if he gets too close.
Best thing you can do is bring a “tank” who is very experienced with the fight. He likes to phasewalk people with the highest toughness. Abusing this behavior let’s you control his position. Controlling his position makes it much, much easier to bring up downed players and dodge his attacks.
I’ve also heard walking in a zig-zag like pattern let’s you dodge the green projectiles without using endurance. I haven’t experimented with it myself, so i don’t know how reliable it is.
30 minutes? I downed him on my last run with a random pug after 7 minutes nearly.
Try to find experienced serious players who don’t pull to the wp. Needs time to gather them, i know.
Worse thing about giganticus is:
The fact you have AI during phase 1.
The shadowbolt attack is annoying.
Other than that phase 1 is rather cake. When we did it had most on range but me + another warrior just swing melee till grubs spawned on us which died fast. Slowed down the fight but really makes sure you get them.
Phase 2 – Kite and live. Dodge etc.
Phase 3 – Can melee him (I did) and just dodge attacks. Got caught in bubble sometimes but was able to get out of it.
Also if you get far enough away inside his room you can OOC regen yourself back up. Just make sure people have agro on him.
Pro tip for phase 2: His mass-AoE has a maximum range. Just walk away.
After a few tries he is no more a problem – and if you really cant manage to pug him, just get yourself a decent enough guild. At this point my guildies are able to zap him with any given class setup in a matter of 10-15 minutes.
