Which category do you want to try?

all of them are done without rolling but breeze harbor is a trouble because I kind of bounce but sometimes Spyro does his walking animation so idk if it counts as stading Edit : Zephyr's portal is possible but insanely hard so that's 10 portals

Video proof :

As for the original Spyro 2 speedrun, there is a category called "stand on 10 portals" and I think it's possible on Spyro Reignited Trilogy too. I've tried and managed to stand on Colossus's, Hurricos's, Sunny Beach's, Fracture Hills's, Icy Speedway's, Skelos Badlands's, Crystal Glacier's, Robotica Farms's, Mystic Marsh's, and maybe Breeze Harbor's but for this one I got a glitchyish result so maybe it doesn't count (Zephyr's might be possible). I think it would be cool to add this category on speedrun.com and I have the video for each portal if anyone wants (done without Roll in Air glitch)
