No, you can’t. It doesn’t. I tried pyro3-link3-ench. Link3 did “nothing” in a party setting other than group mobs (that didn’t die too fast) up. The really low hit limit on [joint penalty] made it so sometimes the links would break even before [hangman’s knot].
For [spiritual chain] to be useful, you need solo buffs from your party, otherwise it literally does NOTHING. Even if you DO have sharable solo buffs like [running shot], [surespell], [quickcast], [gung ho], these buffs have to be usable by everyone else they needlessly use up a buff slot or erase buffs your party does use.
[lifeline] is only 50% uptime and is really only usefull on “pure builds” otherwise it is a marginal increase. The uptime on it means at best you want a pure INT build with a pure SPR build in the party to get max ench damage on both buffs for maybe 1k8 elemental damage. [lifeline] will get use out of a really organized party (one that factors in stats, class comp, etc).
Linker does however shine in solo play + ST (single target) builds. The dagger build in particular makes great use of linker.
