Items
We've revisiting Bami's this patch to help keep it in line with Fated Ashes, which has seen a clear dominance between the two options. We'd like the difference to be less decided between the two components for jungle clear power, so these buffs should help do just that.
General
- •Immolate monster damage increased to 200% from 150%.
- •Minion damage unchanged.
General
- •Immolate minion damage increased to 160% from 150%.

When you find yourself forced to rush a QSS to survive an enemy Malzahar, Warwick, or just a team with heavy CC, it's still usually in your best interest to complete this item last. Even then, you still may feel like you're giving up more power than you can afford due to the meager stats that the item gives on completion. We're looking to make sure the item still feels appropriately tuned while keeping a focus on the active as its main strength.
