So I’m still confused. For ascending troops you need several to sacrifice. Apparently the rate is 5 to 1. However, some have stated here that you need 1 extra copy of a troop, because after all you need a troop to ascend. On the other hand you can reason that by sacrificing 5 troops you sort of MERGE these into a new, higher rarity troop.
The issue is coming up now, because I am going to buy The Anointed One, and need to know whether I need 5 or 6 copies.
For the latter theory I think I have found proof, because in the preview video you can see that Goblins are forged into a rare Goblin. For that FIVE are used, not six. QA Cat starts with 131 Goblins and afterwards there are 126 left (arrow pointing from 131 to 126 in the video, at 1:26; 126 rare Goblins at 1:43).
