Each Ancient Soul earned is worth a tiny bit of Transcendent Power.

Transcendent Power increases the Hero Souls dropped by Primal Bosses. Transcendence does not replace Ascension: each Transcendence cycle is worth and will require several Ascension cycles, increasing as your Transcendence rewards do. Purchased gilds are only temporarily lost: you regain 5% of them every time you earn a gild normally. On mobile, however, Mercenaries will still be available post-trancendence. Mercenaries will be locked immediately post-transcendence, but will be kept in store 'as-is' and unlock at the normal time (level 139 or after one Ascension) and remain just as they were when you left them. This makes it easier to level Outsiders, and fix mistakes. It is always recommended to Respec on Transcension. Unlike Hero Souls, all Ancient Souls are earned back when respeccing. You can choose to respec when you transcend: simply tick the 'Respec on Transcension' when you transcend.

Transcendence becomes available after defeating Woodchip, the Rodent (boss of zone 300). In exchange, you receive Ancient Souls (which is based on the total amount of Hero Souls sacrificed) and Transcendent Power. Transcendence is basically a super- Ascension but in addition to sacrificing your Gold, Hero levels, Relics, and zone progress, you also sacrifice Ancients, Hero Souls, and Gilds (except gilds purchased with Rubies which you'll gradually earn back). Sacrifice everything to appease the Outsiders, and gain previously unheard of things.
