When doing wessons mission do you get to keep the enchanted Curis he sends you after when you return to him

No. You can delay turning in the quest if you wish to use it, though.

Ok that was the last of my missions....the hall of echos awaits me again....though i might want to stock up on potions lol

If you want to stock up on potions, the quickest way to do so is to head to a small location first (like a house in High Hall, for example), to cut down on the loading time leaving the battle tower.

Runners and Tower ? / Very low success rate with Fanny Blossom?

Raze's cuirass is terrible stat-wise, though. All it has going for it are the three enchantment slots, and that's not enough to make it worth using over things with better stats.

Also, you do not need to make every new post a Calendar event. That tag is only for well, special time-limited dates that need to be marked.
