The AI Computer begins its targeting based on Affinity.
Leader: Thenasil - Dungeon Aura - Resist 70
Front Row: Skills
Warmaiden ----------> AOE Def Down
Thenasil --------------> Healing + Increase Defense
Umbral ----------------> AOE Provoke
Back Row: Skills
Kael --------------------> AOE Damage + Poison
Cardinal ---------------> AOE Revive
The team I recommended to you has the following Affinity Attributes:
Warmaiden + Thenasil = Force
Kael = Magic
Umbral + Cardinal = Void
Stage 13 Dragon Dungeon is Magic.
Magic Affinity has an Advantage over Spirit Affinity.
The first target for the AI is against Spirit heroes.
Your team doesn't have any Spirit heroes.
This means it will shift the AI priority.
The AI Computer will begin targeting heroes which are Neutral Affinity - Magic & Void.
The AI Computer will go after 1 of 3 heroes Kael - Umbral - Cardinal
If there is a tie on Neutral Affinity Targets, The AI Computer will begin attacking the one with the lowest HP.
It attacks the one with the lowest HP because it thinks the hero is fixing to die.
You need to make sure Umbral has the lowest HP + highest DEF.
You can't guess that Umbral will be the lowest in HP.
You have to make sure she is the lowest in HP.
Or the waves in the Dungeon will attack your Kael or even worst your Cardinal.
Than your run will be a total bust.
The set up I am telling you is trying to trick the waves in the dungeon to focus on Umbral.
Umbral will be the punching bag.
Umbral will need to have insanely high defense.
You need to make sure your team health is higher vs. Umbral outside of the battle & inside of the battle!
Take heed to when I say outside & inside the battle!
Sometimes, the AI will do a random hit / curious hit is what they call it.
It is usually 1 unit in the mob which has a curious tendency to hit alternative targets.
This curious hit on the surface doesn't do much if you build your team right.
However, If your Kael or Cardinal get hit with this curious hit, You need to make sure you have a health buffer.
If there total health in the fight drops below Umbral health in the fight, The entire mob will shift there target focus.
They will begin seeing Kael or Cardinal as the "lowest in health."
What do I mean when I say health buffer?
Well lets say the curious mob hits for 4k health.
You would want to have over 4k health difference between your Kael + Umbral.
Your Kael could have 25k HP.
You Umbral could have 20k HP.
Now if you get hit for 4k HP.
Your total health would go from 25k HP in the fight to 21k HP in the fight.
BUT notice how 21k HP is still higher vs. Umbral 20k HP.
So even if Umbral was at max health in the fight - The mob would still register her as the lowest health unit.
