[Star Wars] How do you recharge a blaster? And how many shots before you need to?
gpt
Blasters use two consumables:  tibanna gas and a power pack. The pack is basically a battery while the gas is what actuality gets fired out of the weapon. Power packs can give a variety of number of shots, depending on the make/ model and how much power your blaster draws per shot. The gas lasts much longer than the packs but still does run out eventually.
