Labyrinthos Raid 135 Solo: Revelation

After months of soloing Raids, most soloers are sick of this anyway. So let's just all solo this now. lol
Forbidden Land: Flame Trap Method
Spear Main + Valkyrie + Taoist.
Burning snakes for fun. This is probably the easiest way to kill the boss here even with low gears. Ever seen 813K+ damage?
Sunless Forest: Vampiric Insurance
Spear Main + Tarkan + Vampire.
Sometimes the NPC's HP goes dangerously low that having a healer as insurance would be nice. So why not take the Vampire since not only can she tank much better than a staff merc but can also kill 2 mobs at a time.
Battle of Red Cliffs: Solo Power Trip

One of the longer TBSs but it's fun to do this once in a while. With 4 Bosses, 3 Summon Gates, several minibosses and hordes of mobs, it has its fun moments.
Forbidden Land: Attack of the Evil Monk
Spear Main + Monk + Tarkan.
Monk hits like a drunk old man but it takes a lot of turns to beat the Boss here that he is actually useful working together with melee mercs.
Ravenous Valley: Awakening Master Monk
Spear Main + Monk + Tarkan.
Here I tried using my evil Monk in TBS for the 1st time for lols. It seemed mobs fear him so much that they went for him a lot.
Jungle of the Beast: Alternative Spiking Mercs
Spear Main + Hwarang + Champion.
The objective here is simple, kill the boss at the top right of the map. You can safely ignore the two other bosses.
In this sample run we also had to fight against the deadliest debuff in-game, Item Lag. Had my team stunned and unable to awake for some time.
Nest of the Empress: Alternative Spiking Mercs

Hwarang is a good substitute if you don't have a Tarkan as long as you bring a DEF debuffer here. In this run I used Ody as debuffer and Hwarang and Spear Main as damage dealers.
For less stress I'd suggest having double feast (NC+Unity) buffs and Chaotic Ruler title when running this.
Spirit God: Mob Control and Boss Spiking

I wouldn't recommend soloing this mission if you can't kill Dogon bosses within 4 turns at most. But if you can, then there should be no problem.
Nest of the Empress: Short Version

The plan is to go straight to killing the Boss and skip having to destroy all 3 beehives (summon gates).
For this you'll want 1 melee tank, 1 damage dealer and at least 1 DEF debuffer. Ody would be great with his best in-game DEF debuff, Shield Bash.
