Question: destiny 2 how many kills for thorn?
Answer: As with the last step, bounties and kills yielded five Plasteel each, while the Blind Well was quicker--it kicked out 10 Plasteel with each Heroic completion. You need 50 in total, so five Blind Wells will do it, and this is a good chance to check off your Gateway Between Worlds weekly bounty from Petra as well.
