Don't know why these haven't been posted yet (some have been half-posted, but nothing straight-forward).
- Magmacite event. Have someone run across the lava, Magg will die, everyone else Waypoint back to the beginning of the instance, Magg will rez @ Magmacite and the instance will continue.
- Bomb event. You can hop through the right side of the wall blocking you from entering the Flame Pillar room. Kill the Pillar and you'll skip the final boss and get double chests at the end.
- Bomb event. Talk to Magg, let him die. You have two choices from here. First is to rez him with an Ele's Glyph of Renewal over and over (he will tele to the Ele every time) so you can slowly move him out of the room. Your second choice is to rez him and then pull one of the pats from the previous room (Charr and his lizard pet) over to Magg, he will aggro and chase the Charr/Lizard out of the room, once he's a safe distance away from the room talk to Magg to start the event (you can kill the Charr/Lizard at that point).
If you've got any more let me know and I'll add it to the list.
Also note, some of these may be fixed on Monday when they patch the dungeons. If you need some CoF tokens do CoF now just in case.
