The Siren will charm the Leper and you have to move him to the fourth slot.

Like other bosses, the Siren increases stats after raising her level.

He sold the Siren to the monsters from the Cove and a harmless girl turned into a terrible nightmare.

Now the Siren is a queen of the Cove as well as a slave of this place.

This ability allows her to gain control of a certain hero for two rounds.

A charmed hero will use all his skills even if you didnt unlock them.

After returning a character will be located at the tail of your formation and also will get a 20 resist for all debuffs.

The Siren always chooses a target for her main skill with the lowest resist for debuffs.

She doesnt have any lethal skills or abilities with terrible status effects.

And you can dodge her Song of Desire although this skill has big ACC.

You can simply focus on the boss and damage her every turn to end the battle quickly.

However, we suggest a more balanced strategy that will definitely lead you to victory.

It will increase resists so the Siren cannot cast her Song of Desire.

Dont buff just one hero because he can be charmed and will use these buffs against you.

Charmed heroes can cast all skills so fill them up with heals and buffs.

The Crusader and the Leper can be useful for your team even on the enemys side.

The Siren is eldritch so you will damage her more efficiently.

And your team doesnt include eldritch, yes Here you can take the Occultist.

You can damage the Siren with this bonus and it will not affect your mates.

Summoned minions also dont have bonus damage against marked foes.

Just be sure to stun betrayers and summoned enemies and damage the Siren itself.

Now the boss will always focus the least protected hero and the Man-at-Arms will always dodge her Song of Desire.

Easy.

Also, you have to take some heroes who are dangerous in certain slots.

For example, you have the Leper with low resistant and the Bounty Hunter.
