Oh, sorry I was talking about d.ring.
Average number of kindred seals required to obtain a d.ring.
5% drop rate on HQ pop (1/20) and 5% drop rate on d.ring (also 1/20) works out to be 1/20 * 1/20 = 1/400
400 orbs * 99 k.seals = 39,600 kindred seals.
Like I said though the drop rate with th9+ is closer to 8% so it'll take fewer than that.
