Can we do this for Liandry's

Add base or minimum damage.

2-4% of 50 health is still just 1-2 damage. 2-4% of 4000 health is 80-160 damage. It hits 3 times. So 2-4% of health after the first spell's impact. Then 2-4% of what's left. Then 2-4% of what's left.

The damage declines and eventually falls off. The item's design is that it is supposed to shred high-HP targets, yet the frontloaded burst of a spell means that the impact of the item's dps declines. The burn is ineffective for killing blows and makes misses a more frequent occurrence. Adding a base or minimum damage to the burn could ideally make this item still have an impact on reduced health opponents while not too heavily punishing low-health enemies.

Just saying that it shouldn't be an item that completely punishes you for melting a tank faster... since that's pretty much it's entire purpose.
