Create your sinner

Ive been thinking for a while like what if they release 2 sinners at the same time but they also go really well together like they’re husband and wife , bro and sister it doesn’t really matter but their abilities and passives combined like one is endura and the other is umbra and when they are close to each other they grand each other buffs, both get bonus armour and dmg. Endura can taunt enemies in a cross aoe and buffs the Umbra and umbra deals 3x3 aoe dmg idk smth like this. I have also thought about a sinner who can revive other sinners but it would be too broken and pretty difficult to add it to the story anyway lemme see new ideas Im curious how broken of a sinner can we make.
