When a 19 casts lifeblood from a skill level of 225 herb they gain ~26% haste which is really close to Heroism/Bloodlust's 30%. I'm a fan of the sound that happens when Heroism is cast, so I've created this simple macro that will play the Hero sound as you pop lifeblood, I find it amusing and fun to use tbh.
