[Limbus Company] Hard MD solo - Blade Lineage Faust

Starter gifts recommended are first 2 of Rupture so you have high speed and can clash first in normal encounter to avoid taking unopposed damage too early, also tons of damage up. Faust gains Poise easily so no need for starter Poise gift, can happen upon Cigar Holder by chance later.
First 2 stages are simple, pick pack that the Sinner have resistance against.
Can try and aim gifts that generate EGO resources for EGO spam in case of tough normal encounter.
The other stages follow similar approach, if lucky and get Melted Eyeball, should aim to get Downpour and enhance it twice, allowing a -10 offense each turn to enemies which translated to not only a +3 clash power but also reduce their damage dealt, all done passively without the need to attack or deal damage, an excellent combo. Another great item to pick up is Carmilla so floor 5 will have an easy time with the mobs due to staggering them before they diss out too much damage.
