Trying to get all 50 assaults done, im sure lots of people in this same situation, where theres alot of Tier6-10s not completed because of spamming easy low tier assaults for points. Now its always easier to get a 3person run goin, so keep this to Tier6-10 Trio strategys please. These are the ones I know of to start it off:
Tier6: Ilrusi: Apakallu Seizure: Basically you need to get only 1 apkallu to the end point to win, you have to sneak up behind them, use emotes, capture them.. then escort them to the point while staying just behind them the whole time.
Tier6: Lebros: Apkallu Breeding: Only need to match 1 pair for win, use a guide needed to translate the "morse code" they use to match a pair.
Tier6: Mamool: Imperial Treasure Retrieval: Find a treasure and return it to your base to score a point, avoid mamools. Easy win and added points the more treasure you get back.
Tier7: Mamool: Blitzkrieg: Killing 1st wave of mobs only required for win, best set up is RDM, BLM, and a good DD/NIN. Mobs have very low hp and weak hits, but you will fight 200. Phalanx2 DD, prepare for long fight at start, when it gets packed with mobs -ga3s will drop all of them. Blu works great with aoe spells, battle dance etc, any melee with aoe WS is fine.
Tier7: Periqia: Defuse The Threat: Avoid quirin altho easy to solo, must locate and defuse/blow-up 15 bombs, just go around til you see message then click bomb, quite simple to trio.
Tier7: Ilrusi: Lost And Found: 1 person controls npc, you follow it and take its clues. Spam tab and look for ???s and click them fast, eventually it will tell you who the ring is closest to then its simple.
Tier7: Lebros: Wamoura Farm Raid: Kill all mobs. Do south first then work north, the 3 paths at the top of the map: only 1 will have mobs. 2 DD/NIN + BRD probably best, I believe 2 blm + brd, or 3 blm could pull it off to. Better to try n bring a 4th for this 1 but its definatly trio possible with the right amount of DD.
Tier8: Leujaom: Imperial Code: 3 NM fomors must be killed, done this multiple times trio with brd blu nin, anythin else like rdm + 2 dd would be fine. Basically sneak around the map to find the NMs, try and pull the weak fomors by them first, If NM links you must kill first it wont sleep.
Tier8: Ilrusi: Deserter: Only need to 'break" 1 of the mobs weapons and then goto npc and exit, use critical hit WSs, thf or /thf, for the melee.
Tier8: Lebros: Egg Conservation: Very similar to blitzkrieg, just have melee with aoe WSs, this 1 you have to protect female apkallu, all but 1 can die tho for win.
Tier9: Leujaom: Red vs Blue: Need 1 leech to stay at start to activate npc when rdy, 1 to aggro all the mobs, and 1 to solo the NM. It can be solo'd/duo'd many ways, easiest way being identical to how a blm would solo a pudding, nuke grav nuke etc.
Tier9: Mamool: Azure Ailments: Basically fight a different kinds of mobs til you are affected by an ailment, then go talk to the npc with the ailment still on, must do 5 for win.
Tier9: Periqia: Wake The Puppet: Any 2 DD + healer can do this np. You start in middle, there are 4 rooms at N E S W, each will have 1 or 2 puppets, theres 6 total, only need 4 in for win. Go to a puppet, once 1 person /salutes it they control it and wights will pop, 1 person pull a wight to the pup and the person controlling sics it on the wight. Now just everyone run to the start npc, you will aggro a few wights otw back, when at start kill them there (they are easy prey to 75) and end the pup you are doing. Repeat til you get 4 in.
Tier10: Mamool: The Susanoo Shuffle: Hydra: Beaten with 4 np, 2 nins and rdm brd. I do believe still possible to trio by just removing a nin, long fight yeah but you got 30mins.
