Day started with some cobalt runs. I had to teleport to Dralk, then run to cobalt fields, make cobalt bars, run again and teleport several times. Of course, it took some time -but my Armorer benefited from that. While I gained no xp from Steel - cobalt gave me decent one.
When 200 Cobalt jointings were added, made several runs to make enough bars for some 100 cobalt sheetings. After that had to make some Steel sheetings - and metal part for one silo was complete.
Then I switched to Mason and went to maze-like mines of Aughundell, avoiding golems (to increase my own capacity, I did not take any weapon or shield) to the field where I had motherload of granite, several rich nodes and even two "walking nodes" (i.e. golems should I have at least some weapon). Crafting was easy one, with only one time Golems chased me.
I gained no experience from making Granite bricks from slabs (a pity), but did gain some from making keystones from the bricks as well as from adding them to the structure.
In the midtime of harvesting managed to make one steel tool for Player D. - at least somehow helped others.
And the day ended. Tier 4 silo is by ~60% finished. All that remains are granite blocks and Obsidian blocks and keystones. I also gained some 3 levels as Armorer and almost 1 level as Mason. Not so bad: finishing this silo would give great xp to my Mason. And yes - there are 5 more silos to finish...
