There is no official spell with the name Drain Life. It must be homebrew -- if you didn't make it you'll need to figure out who did (if the character that has it is in a campaign, it was probably made by someone in that campaign) and ask them to fix it, or if you made it you'll need to fix it yourself, which folks here can help you do.
I'm 5th level and it should be 2d8 but didn't change to add another dice
