Recently I have obtained enough mats to ascend two nature 5* characters and one Dark one.
Dark Heroes to consider:
Kunchen, Marie Therése, Zulag, Domitia+Cos, Sartana
Leveled Dark Heroes:
Khiona, Alfrike, Freya
Nature Heroes to Consider:
Jade, Toxicandra, Francine, Lianna+Cos, Kadilen, Bertila, Zocc
Leveled Nature Heroes:
Mother North, Yunan, Elkanen+Cos, Gregorion
I have too few Dark characters fully levelled so there is a lot of room to grow. Marie Therése seems overall more powerful than Kunchen by 10 points, she can damage all enemies when she heals, resurect (kinda), provide increased defense, I have a small pile of monk emblems already, where cleric emblems are all hard to come by, and she may is rare to see on defense, so she could be a bit surprising. Kutchen seems more logical as he is still widely used in top 1000 teams, instantly heals, and resist holy and seems like a good successor to Rigard+Cos+20, who has been needing replacing for a while. Though filling the dark healer gap is good, my only sniper-ish character is Khiona, so Domitia also seems a good choice.
Francine, seems likely, as I have Vanda 4.80+19 already and the family bonus could be useful. Though I have no other 5* ninjas, Jade seems like a fine choice in absence of Kadilen+Cos since I have enough monk emblems to get them up, she can provide dodge and rob mana, meaning she could prove a fine green tank. Gregorion is an okay sniper, but a faster Lianna+Cos could prove more welcome in green teams/titans. In all this, I now have an unexpected wind fall in Toxicandra. Though I have one 5* healer already, the mana boost and having the rarity of a fast healer, and a potentially tanky one is hard to resist.
I welcome your thoughts, especially if you have experience with these heroes. Which two Nature characters and one Dark character do you feel have the most potential?
