Strategy Guide

If you think the battle with the Trojan alone was challenging, think again. This time he is accompanied by Chio. Even though she only has one attack, her Vine Grow ability is particularly dangerous. Not only are the damage and range extraordinary, it is White natured and can destroy characters like Death or the Fool easily. Luckily, she will only attack the characters that are closest to her; therefore, plan your moves carefully to spread out the damage.

Use the same basic strategy that was used the last time you encountered Trojan. Have Emi support the party with Lightning Aura since her abilities deal very little damage to both Trojan and Chio. Emi actually makes a decent tank against Trojan due to her Yellow immunity.

You should avoid their range on the first turn, but don't play too defensively. If Trojan decides to charge your party, it is a good chance to focus fire or disable him with Soul Ritual. It is advisable to take out Chio first, but as long as you don't spread out the damage, you should be fine. Consider conjuring the High Priestess after you have Soulbursted Death. Her Essence of Life can render Trojan's Thunder Beam almost completely useless.

If you were following the power build for Gelyan and have the Marksmanship Perk on him, use Gelyan to snipe Chio. He can damage her severely and out-range her. The Magician can also use Meteor Strike to hit her from afar without the fear of retaliation.

Tips for this battle:

After this battle, Sisily will get a new battle ability called Warp Tornado. Warp Tornado is similar to Crystal Ballad since it damages enemies both magically and physically. In general, Warp Tornado is weaker than Electrify Kisses but has a higher hit rate. Warp Tornado is effective even if the target has a high resist.
