We certainly get a good choice for our body seals... lol
I got the vast majority of mine through Amarok as I was working on upgrading up Twashtar. The problem pop item is the Tiger King Hide which can be found in yellow boxes in A-Altepa. You could do that in your spare time. (Admittedly, I did this in a glorious attempt to avoid spending money on those hides. I just farmed the zone for a while and if I got a hide I would D-box it to myself and go back so I had a stockpile.)
The Ironclad in A-Uleguerand can be a massive pain. It is usually best for a single person to fight it at its spawn point whilst being bombed by a WHM, and just have trigger jobs time between swings. In my experience, I'd strongly avoid kiting it as it seems to trigger Mighty Strikes/Invincible.
The Ironclad in A-Grauberg isn't nearly as bad but the same applies. If you want to go the quest route to supplement your body seal intake, try this one
. It's very easy: go to #4, activate it, hop to #3, murder the wyverns, get item (quickly, hopefully) then hop back, zone, repeat. No need to spend money on that if you have some patience. The quest
in A-Altepa is easily soloable by DNC too. The target NM isn't anything special.
