This chapter is just brutal, and there's no easy way out like 25, avoiding Iago's Hexing Rod is easy as he follows a pattern, the problem are all the Maids around the map
The first room has one with a Hex Rod too, Silenced her and stacked up my units on the door on the first turn(you may avoid Iago's Enfeeble as there's only one tile where he'll be able to hit you) and charge in and kill her and the Heros in the second(Freeze is no problem after you kill all the enemies in that room)
There's a Maid with Entrap in the room fo the right with two Sorcerers, do not get within her range on turn 1 with anyone but a paired unit that will be used as bait and to kill the mages earlier
Before going into the next room, you'll want to send a Staff user to the south of the room and Entrap Hans(his Res is low enough that it's easy to get +90 hit on hum) and kill him, preferably with Xander at 2 range as it won't activate Counter nor Countermagic and has WTA, in the next turn, reinforcements will show up to very south of the map
Now there are two paths to take, protip: DO NOT GO THROUGH THE LEFT PATH, I REPEAT, DO NOT GO THROUGH THE LEFT PATH
Faceless have Poison Strike and Seal skills and Stoneborns have 5 ****ing range and are too ****ing bulky, meanwhile, the right one has only Sorcerers and two Maids with Freeze and Enfeeble(the only reason for you to take the left path is for the Spy's Shuriken but it's REALLY not worth the trouble)
Stack up your units near the door, stay out of Iago's range in the Hex Rod turn, pray that the Maids freeze a support unit, break down the door and kill the Sorcerers. There's a Sorcerer with Tomefaire in a room south to this one all alone, bait him out through the door or just kill him after breaking through the door, he's the smallest threat of the entire map
Now's fhe tricky part, the reinforcements triggered by attacking Hans and the two Generals near him will walk to the door and attack with Spears if there's anyone adjacent to it.
You DON'T want to break it now, you should first kill all of these that rush at you so the amount of units you'll have to deal all at once later is manageable.
Rack up those rallies and sings because you'll be here for a while, Xander could take some hits but couldn't kill the Generals before the Maids healed him(thanks Wary Fighter!) so my strat was "seal Def, rally everything, attack, sing, attack and hope for a crit", after killing the 3 Generals and the Berserker, all that's left should be 4 Generals, 4 Berserkers to the left of the room and 1 General and 1 Berserker from the reinforcements
Oh, and that's not all! 3 Sorcerers and a Maid will show up on the north and west of the eastern room, don't worry, one of the groups will wait a turn
Break the door and have your two bulkiest units block the passage, they can't be mounted because the Generals have Beast Killer so unless you reclassed Xander, I hope you have Effie or Benny on standby. Btw, the Berserkers have Hanmers, have fun!
The Generals or Xander should be able to tank the enemy Generals though, after that, charge with everything you've got while hoping the Maids didn't **** your strat up and kill as many things as you can and try to not leave anyone in the Maid's attacking range(they don't need to be killed right now anyways) and also make sure to have someone deal with the Sorcerers from earlier
After all is done, kill the Maid on the right and be careful who you send to kill the one on the left because there's no way to attack her without getting into range of another Maid with Entrap that will pull your units to a room with a Faceless
Elise just died like this, don't kill your little sister like that
And FINALLY, Iago himself
Man, **** him, if this map wasn't Hard enough already, he just HAD to have a high crit Tome, just use some Brave weapon on him so you can kill him before he even has a chance to touch you
Now, enjoy the loot, get that gold, give that Seraph Robe to someone, make sure to enjoy those S-Rank weapons(*Witch Avatar with 42 Mag laughters in the distance*) and sell that Bifrost staff because lol S Rank on staves
It hurts that Elise is dead tho, no one can use Fortify now and that would be damn useful on Endgam--
I know who's getting that Arms Scroll
