During the Double Rainbow I was able to rank Hillwen Engineering to rank 1. Luckily I had 17 (10%) training seals from the Sky Lantern event, and I was able to use 4 older Caravan Joe (25%) training seals and 3 Advanced (48%) training seals to supplement alongside those. It took me 12 hours in total (material gathering and crafting) to get from rE to r6 with 8x training :] Really glad to have finished, as I had ranked Magic Craft not too long ago too!
