The SL runes Myx Bombardier and Mutated Drake (sidenote: a drake is per definition not a dragon) have Sabotage: Acid which grants Amplify: Acid and Vulnerability: Acid to OPPOSING champions. While for example Amplify: Poison boosts the damage of poison by 10% the tooltip for Amplify: Acid here states that Champs that share race/class have +1 SPD. So apparently something is wrong there. Please clarify.
