I've seen one that does a chain lighting like effect. as well as one that ups your armor a lot. and one that is "refreshing" still haven't figured out what that one does yet. I assume it heals you or refills your health potions. but i haven't run accross it when I'm not full on health yet.

idea on that, did you have the expanded critical perk? maybe you attacked it was a critical and the expanded range let you hit the incinerate button at the same time you picked up the shard? if this is the case this will make it nearly impossible to reproduce consistently. :/

i wonder what would happen if you duplicated shards. corrupted all the abilities while still destroying all 7 shards... hmmm

so on my insane play though I'm doing currently i don't take the same route you did. i literally just went straight up the cathedral i didn't touch the right side of the map at all. so i feel like you could do that instead of going around the long way. its amazing what you can do using the up attack between each jump and wall jump. you can easily climb directly up a wall and if there are enemies attacking you then its even easier to climb directly up. this was all on a full resist play though as well so i didn't corrupt any abilities. I feel like in a speedrun of this you wouldn't get the cannon at all as its not needed. to finish the game. you ¤might¤ be able to skip the air dash, but i use that to climb the cathedral a lot. not sure if going the long way on the cathedral is a time save over getting the dash. you should defiantly be using the up attack more often when climbing it helps a lot.

I've found that just holding up and slightly toward the wall on a controller can just let you repeatedly use the up attack to scale a wall without even jumping off of it. Used that to bypass the double jump ability check ones the start to get to the second battery. But got stuck in a room due to the layout needed double jump without a wall to scale up and cheese it.
