Fought the cactuars tonight and all i can really say is that you need to get your triggers in as fast as you can and zerg it down. Every time it uses a certain TP move it re-summons its pets it levels up and gets tougher to kill. We didn't try stalling the pets and then killing the actual NM. If it doesn't use that move then it might be easier to kill? Also if you try to stun the TP move it uses to summon its pets back it will immediately try to use it again a few seconds later.
We also did the tiamat looking wyrm. This thing is no joke, it will fuck you up. You have to keep up with damage the whole fight or you will time out if you aren't careful.
Things to note about the wyrm:
Uses AoE Absolute Terror and its lasts long as fuck, you need to be @ 20 to be out of range of it.
Its pets will use voidsong and dispel everyones buffs fully. I think they both use their TP moves at the same time.
It will only summon its pets at 100% 75% 50% and 25%.
All standard tiamat TP moves except for roar hate reset I think. I didn't see it use it anyways. Probably does though I'd imagine.
Also has regen like all wyrms do. Goes up by 1% every minute or so.
It will fly when its pets are out, so you have to kill them to get them to the ground. Every time it summons it goes in the air.
