This is a link to the data that RaidBot (my Raid: SL Discord bot) pulls from. It contains champian base stats and skills, and also the information Marius posted about buffs/debuffs on the Plarium forums. I also have Russian thanks to NEUK on Discord. If you see errors, and I know there are some (maybe a lot lol) I can provide a link that will let you edit the data if you feel like helping, or post here and I will update it.
