Summon rush question
So I'm trying to plan out the fusion and I have a question about the summon rush. The champion chase obviously makes sense in that you get points based on the champions you acquire regardless of how you acquire them (campaign farming, fusion, shards). For the summon rush, is it solely points based on shards and not really on summoning? So spend 1 mystery and get one point. 1 ancient and get 20 points. One void for whatever (150? 200?) and a sacred for whatever (500?). So it doesn't matter what you get, only the shards spent? And do fusions (relic keeper and broadmaw) count towards this or is it solely a shard counting event?
I mostly ask because I'm trying to figure out whether or not I should partially skip the 2x for ancients (which I've been a bit excited for as an early game player) or not. If I could use my 2 prepared fusions during the summon rush I'd be thrilled but I'm guessing that it doesn't work that way. I might have enough points for the event even if I use all of my ancients this weekend but I'd rather be safe than sorry if I cannot use the fusions during the summon rush.
