Then maybe Lone Sadi should give each doll something different? For example:
Greedy and Ultra: +Dmg
Inflatable: + Heal
The Block: + Res (or lock, or both)
MP and AP doll: I don't know, maybe more Res as well, to survive more?
So each turn, every doll would get stronger and stronger, not just in dmg but also in support.
As for the Doll Link. Would be cool, but without rising dolls HP they would die even faster than they do now, which I think could be ok IF they would be much cheaper to summon.
I also had a crazy idea about Super Tree build, lol.
Once we cast Tree on ourselves twice, we become a Super Tree. We don't attack, but our dolls get like a super buff. They get more HP, Res, DMG, +Heal and everything and we only fight with dolls while being in that state. We get like 5 extra spells (while the rest is gone) to control and buff them. Like, we can push them with wind in the direction we want, we can move them with our tree branches, we can heal them a bit with healing leafes from the tree ect. Like a whole new build just with dolls.
But it's just a crazy idea
