switch to the class you get marks from start the leve then switch back to your class you want to play and you'll still get the marks.
no, you won't. I tested this already. I lvl my Thm when I'm grouped with my fiancee and my Conj when I'm solo. (I mix abilities obviously no matter which I'm playing). I tried switching to my Conj when I activated the quest, swtiched to Thm out in the field so I could actually fight and then switched back to claim the reward. If you try this, you WILL lose out on the marks completely and get almost no reward for the leve. You need to start, progress, and complete the leve as the appropriate class.
I realize this doesn't make things better for the OP but I thought I should give you fair warning, that's already been tried.
No, you don't. My gf and I do leves together, and she's had leves where she started as a CON, and realized after the leve initiated that she had THM marks as a reward, so she switched and still received the THM marks at the end, so at the very least, you don't have to start as the correct job.
We haven't tried switching to the correct job after the aetheryte shard appears but before collecting reward, but we're assuming you need to be the correct job when the last objective is completed to get marks. Edited, Oct 31st 2010 11:04am by Ilmoran
