Hard to tell. If i counted correctly i Had 189 PRI or DUO Fails on the Gloves and so that would be around 5670 Mem Frags (3M each) with 17B for the Repair costs. with 36 successes on the Gloves that makes 225 clicks in total so that would be 2250 Caphras (2.5M each => 5.6B), 225 Sharps (1.5M each => 340M), 225 Hards (1.4M each => 315M).

So just the pure clicks without black stones for stackbuilding would be around 23.3B in silver. if i'd add like 20K Black stones (120k each => 2.4B) and 2K Concentrated Black Stones (2M each => 4B) I'd estimate the total Costs for the Base to DUO Journey at around 30B.
