I tried searching the forums for an answer to this, but I couldn’t find anything.
Is it at some point beneficial to change e.g., Tiburtus, for a hero of much higher tile damage vs titans?
In other terms, when does the, in this case, -34 def become useless compared to higher tile damage?
In my case, I was wondering about replacing an unemblemed Tiburtus(673 AP) for a fully emblemed c.Domitia with almost 900 attack power.
Against titans, you get the best result if you have the following heroes:
Tile Damage Booster (Miki, Tarlak, Guardian Gazelle, Ranvir or Wu Kong, generally in that order),
Regular Defense Debuffer (depends on the element of the titan being faced; the best against red titans is Athena, the best against blue titans is Frigg, the best against green titans is Santa Claus/Wilbur, the best against yellow titans is Cheshire Cat/Kunchen, and the best against purple titans is costumed Vivica),
Elemental Defense Debuffer (depends on the element of the titan being faced; the best against red titans is King Arthur, the best against blue titans is Evelyn, the best against green titans is Guardian Falcon, the best against yellow titans is Guardian Panther and the best against purple titans is Guardian Jackal),
Heroes that are of an element strong against the titan and that have high attack stat with other benefits, i.e. crit bonus, attack buff, defense buff, etc.
Battle items such as mana pots, tornado, scroll of alteration, etc are very useful also.
You can make a trial and observe the tile damage with both versions, but I think -34% def has far more weight than +300 or so attack.
If you have already 3 or 4 purples stacked your atk may increase from 2000 to 2300, about 15%, -34% def should result in something like +50% damage.
