Record of Lodoss War - Advent of Kardis - Part 13 - Sidequest grinding
I complete (nearly) the medallion subquest here. I leave the Sandworm dungeon since I don't think I have the damage to deal with the boss yet, but you only need 29 medallions for all the rewards. You get the unique Gothic Heaven set, but the real reward is the last one, the Wind Hilt. This sword is as long as the Oriental Sword, but single-handed and very fast, along with surprisingly high Impact. It's only negative is that it does so much less damage, but at this point in the game I can afford that as I start grinding Buster ancients for the extra damage.
At this point, besides the final boss, I have the Sandworm dungeon, the medallion boss, the Gothic Demon trials, the remaining Gothic Dragon items, and the ice caves to do. The ice caves, while essentially for grinding, also do have a couple rewards at the end if you can survive them.
