Having two archers will allow you to keep the silence spell going on a target
After you talk to Lea, head over to the Mercenary Manager. Don’t take this choice lightly. These recruits will be with you for a while. Here are some cabal online alz suggestions:
If your hero is a Cannon, Rifle, Bow, or Staff…choose at least one spearman or swordsman for the front row.
If your hero is a Sword, Spear, or Axe…choose at least one gunner or archer for the back row.
Consider having at least one archer no matter what else you have. Their Silence spell will be a big help against Hellish Fairy in a few levels.
Having two archers will allow you to keep the silence spell going on a target each round, greatly reducing the damage Hellish Fairy can cause to your whole squad via AoE spells.
Click on My Info and then Formation from the top menu bar. You can rearrange your units here. Later on, you’ll get a quest that tells you to do this, but why not do it now? Put ranged fighters in the back two rows and stick melee fighters in front of them for protection.
Return to Lea when you have recruited two mercenaries. She’ll give you 500 gold and ask you to go see her sister, Ellesian. Just head over to the glowing blue tile, indicated by a doorway symbol on the mini-map.
