Bring Multiple Medics

This operation features a map dotted with Heated Paths. You can only place melee Operators over these cells and doing so would cause them to take damage after some time. Use Medics to support and sustain your units so that they can last longer during this fight.

Protect Your Snipers

Protect Your Snipers

Sargaz Enemies will once again appear during this mission. This type of enemies boast high RES, making it hard to beat them using Casters. Use Snipers and support them with multi-target Medics to increase their survivability. Bring 2 Medics to ensure that they last for the whole duration of the battle.

Bait The Sarkaz Casters

By the 34th Wave, Sarkaz Casters that can use a long-range bind skill to immobilize and damage an Operator, will start to spawn. A Medic hit by this attack will be unable to heal, making it dangerous for your Operators standing over Heated Paths. You can use characters to bait the Sarkaz Caster to use their skill as it would take them a long time to use it again.

Take Care Not To Retreat Too Much

One trick to counter the Sarkaz Caster's bind is to have a character take the skill, and immediately replace the targeted Operator with a new one. However doing it too much may drain your DP, making you unable to deal with unexpected threats.
