what kind off acc is needed for regular mobs? In my idel pet dt- set i only sit around 860 personal acc atm. I can switch over to Tali'ah set and get 1048 personal acc, but i lose 21 pet dt-
The monsters in there are lvl 129 I believe, Transcended are probably a bit higher, maybe 131. 1048 is remarkably low acc, especially on beetles. I'm not a BST but I generally sit at around a 1168~ on DRG and Im usually fine. Of course I have a bit of acc traits to supplement. I'd say anything under 1100 acc for omen farming is really low.
what would be some good trusts to use in here?
You should be utilizing whatever trusts will help you accomplish your objectives. There is no cut and dry list of trusts, every job can get away with something and need help from other sets. Here's an idea of which trusts do what:
Cure 500(10): Any WHM trust when you're in yellow will use this. Nashmeira II, Mihli Aliapoh, Kupipi/Cherukiki (will run out of mp very quickly), Ferreous, Unity WHMs. Ygnas is good enough also. Don't rely on Koru/Sylvie/Joachim to use Cure4, they don't have enough cure potency to hit the objective, so I'd dismiss them and let 2 whm's cure you. Also, reward counts as a cure. Don't use a tank trust for this objective because they will take reduced damage and it takes longer to complete.
SC(1): Have to ask a BST for the skillchain path, but if you're going solo, you only need to complete 1 skillchain, so lizard can probably do that on any monster easily. Forget what Impaction is.
MB(3) Use Shantotto II, she can get 2 MBs off per skillchain. If you're subbing a mage job, you can do it also.
Spells(3) Same as above, or Koru/KoH/Adelheid, or any PLD trust tank will flash.
Abil: Easily completed by either removing your pet and using useless ***like tame/charm/steps, or just have your tank trust voke. Or you can use sic if its the same thing as assault on smn. Either way, easy to finish.
Melee Round 2000: You may or may not have trouble with this one. Possibly your Tiger if you Familiar/Run Wild or whatever and get lucky on a DA/crit or something. Can use Koru to apply DiaIII at the start of fight, and Qultada will follow up with Light shot. If there's a pet that can TA, would certainly help. Otherwise, you'll have to get your DT set on, grab Qultada for DD buffs, and strap on your multi-attack set. If you're /dnc, helps a ton.
15k nuke - BST can't do this one, trusts won't help
30k MB - BST can't do this one, trusts won't help
WS(5), PWS(3), MWS(3) - all easily obtainable on bst
30k WS - use any buffing trusts (like sylvie/qultada/Koru/Joachim/Ulmia). Not sure what the skillchain BST can do to set this up, but having your strongest WS+SC closing it is best way to accomplish this solo. You may have trouble with it with your current BST.
