NOTE: About to update for iTOS, note there are two sections: iTOS and iCBT2. I’ve also included the old iCBT2 info for recording purposes. Apparently, many buffs have been changed from spreadable to unspreadable, unfortunately.

---------------------------------------iCBT2 Info -------------------------------
All the skills here below have been personally tested by my linker, and I will indicate if something is from someone else which I haven’t personally tested with an asterisk*. I am going to automatically exclude buffs that already buff the whole party.
List of buffs that can be passed down the chain:
The general rule is that only self-casted buffs can be passed down.
Swordman: Gungho, Concentrate, Restrain, Pain Barrier, Guardian, Cleave, Frenzy, Warcry, Trot (must be mounted), Double Pay Earn, Deeds of Valor, Double Weapon Assault
Archer: Swift Step, Steady Aim, CLOAKING!!!, Sneak Hit, Evasion
Wizard: Surespell, QUICKCAST!!!, Transpose
Cleric:
List of buffs that cannot:
The general rule is that party buffs cannot be passed down the chain. This includes things like Priest buffs, Thaum, Enchant Fire and stuff like that. So I’m afraid you can’t use chain to bypass the distance limit of those skills.
Ground based buffs cannot be passed down - Diev, Safety Zone, Patron Saint and the like.
Channel buffs are not really buffs either (Undistance, Melstis etc)
Secondary buffs will not be passed down (Potions, Dumbell, Squire Food etc)
Swordman: Cross Guard, Finestra, High Guard
Archer: Kneeling Shot, Camouflage
Wizard:
Cleric: Fade, Safety Zone, Guardian Saint, Zalciai, Statue of the Goddess Ausrine, Bokor Flag buffs, Out of Body, Transmit Prana, Iron Skin, Golden Bell Shield
Special notes:
(1) Attributes of the skill do not get passed down (like for example, Swift Step crit) BUT if the attribute is something like +number like Concentrate then it will apply the same number (+77 dmg, for instance).
(2) If you leave the party while chain is up the buffs will no longer pass on
(3) Going beyond the 5 buff limit without Daino will cancel previous buffs, like normal
(4) Skills must be casted after the chain for it to have effect. Existing buffs will not be passed down
(5) You can use someone else’s spiritual chain to pass buffs. But you can only use your own spiritual chain to pass Life Line (Umbilical Cord)
(6) Spirit chain may have a chance to break on uneven platforms
(7) Sometimes, spirit chain may not pass buffs. It is as if you are not in party with them at all. Seems like a bug
(8) If you recast spirit chain while Life Line is up, it cancels the Life Line.
Finished testing swordsman and wizard tree buffs, still need to test archer and cleric. If you know of any buffs that can or cannot be passed, post them below, thanks.
