simple rageblade idea
Its spellvamp and lifesteal is doubled if your afflicted by healing reduction from any source be it
,

.
It won't make you invulnerable to healing reduction, however.. So if you have another lifesteal item or ls/sv quints these will still be reduced. Let's say I equip botrk and rageblade, botrk lifesteal will still be cut in half by healing reduction but rageblade's will remain the same essentially. Give people a reason to want to equip rageblade over botrk or triforce aside from being named jax.
Overall gives you a bit more dependability on it as a source or sustain, it also suits its identity as an item since it only gives sustain when below 50% health which is when morello kicks in, when surge is activated you'd want it count otherwise its pretty underwhelming.
