When Linker links allies together, the effects from potions or buffs can
be shared each other and the damages received by monsters can be
reduced.
So what potions can be shared?
I tested out some buff potions and it doesn’t work.
You answered your own question, i never heard Spiritual Link share pots buff, they do share the cast buffs.
Read TOS BASE Class general description.
You should pay attention to the skill in game, not a description in a fan site, they took that from the original source yes, but that is not implemented in game as far as i know, and if they will do that in the future i am not sure either.
well the description in game isn’t great either, but in any case I hope they implement that in the game.
Another big question is, do monsters share de-buffs. If I use joint penalty then use sleep, does all monsters go to sleep?
I would guess that could come in the shape of an attribute, but i am not sure either lol.
We can only wait.
