User blog comment:Slashingstrike/Enchantment Bloodreaper - jungle item concept for AD junglers/@comment-36072697-20180922134645/@comment-15077371-20180924092644

Riot makes jungle items weaker than their laning counterparts

For instance has 90 AP and does 100 magic damage. gives 80 AP and does 60 magic damage

You probably misread but the bleed damage is based on target missing health. The more health they are missing the more damage it does

the passive does 10-60 phys damage based on target missing health (or 10%-40% AD alternative). This is calculated each second
