9 lives works with The Lost

[Izaya]

just beat isaac with The Lost with a guppy trans, and holy mantle carry.

Just FYI 9 lives does work with The Lost, the x9 doesnt show up but you do in fact have 9 extra lives.

I didnt know when i played so i had to perfect clear it until isaac where i thought i died.

just a friendly reminder, enjoy Rebirth!

Yup, many people already restart runs until they get it. Before patch 1.02 it made The Lost completely invincible after his first death.
