For cantina energy I was doing TFP last night but decided to switch to Old Ben today to hopefully get enough shards to take him to 7* immediately if he's needed for the next step of Luke's journey. I didn't really keep track but I think I got around 16 shards from a little over 100 cantina energy. I'm a little low on crystals so I haven't bought a refresh yet until I can see if I can get a crystal pack. I still haven't replenished my crystals from the double drops earlier this month.
For regular energy, I'm trying Sabine's hard node, got 2 so far. But again, the lack of crystals is hampering me a little. For gear, I'm trying to get stun guns for Biggs to take him up a gear level since I have to wait for furnaces for Wedge anyway.
