Cassandra is a full support hero, not only she can do heal, she can also do buff and debuff. Use for Divinity Chronicles.
Team build: Flora or Oberon or Tamamo no Mae, Izanami, Susanoo, Athena.

Her ultimate is the Pious plea. Cassandra prays to recover all allies to their max health in the 5 seconds, after this health is gained seven percent of the amount recovered will slowly drain away, total amount of health gain cannot exceed 400 percent of Cassandra’s attack. At level two sixty percent of the amount recovered will drain away, etc. This is actually good even in early game, you can use Cassandra if you were starting out on a new server, because she is definitely a good support, she can rival Nagakanya in terms of survivability and effectivity in the team.

Active skill, the Holy illumination, Cassandra releases holy energy at the target nearest to her, these energy then bounces to three other heroes nearby recovering eight percent of max health, if ally or dealing 100 damage if enemy. This energy or holy illumination can bounce to your teammates or to the enemy, so it can recover if it bounces to your teammates or allies, it can damage enemies if it bounces to enemies. At level 2 the energy is conducted up to four times and that means it will bounce up to four times. Level 3 recover ten percent of max health to allies, from eight percent it increased to ten percent. At level four deals 110 damage to enemies from 100 to 110.

Next is the Breathless prayer. Cassandra prays for the ally with the lowest health. For the next three attacks this hero recovers five percent of their max health each time they are hit. It’s actually another healing skill. This is a single target heal.

The Guardian spirit is the passive of cassandra. That can only be triggered if Cassandra dies, so what will happen is after Cassandra suffers lethal damage, she turns into an angel to heal all allies for 12 seconds. Can only use active skill during this time. So once Cassandra turns turns into an angel, she can still use the active skills but not the ultimate. She can still do some healing. At level two reduce damage taken by 10 percent to neighbor allies, so that’s a buff. At level three last for 15 seconds, at level four reduce damage taken by 20 percent to nearby allies. So once Cassandra dies, she will give buff to nearby allies as well as giving healing skills.

Weapon – Fatesfury Crystal Ball.
So the first at 100 increases ally heroes healing received by two percent whenever they are attacked and it can stock up to 30 percent. So this is a passive, it’s like another skill reduces enemy heroes healing received by two percent whenever they are attacked. It’s like Persephone’s debuff to enemies that reduces healing received by the enemy, so this is pretty good for bosses that is healing hard or if there’s a lot of healers. As long as your hero is attacking those enemies, it can stock up to 30, so that’s how good the debuff of this Cassandra. At 200 increases targets healing received by 30 percent, at 300 reduces targets healing received by 50, at 400 increase all ally heroes attack by 20 when their health is above 50.

This weapon upgrade doesn’t have any requirement as long as you learn or upgraded the unit or the weapon to 400, it will already be applied instantly in every battle. So imagine, if you have a 400 weapon on Cassandra at battle, when the battle starts you will already gain 20 attack.
