Illrigger: Soul's Doom damage rider

Recently encountered the Illrigger's level 13 Interdict boon, Soul's Doom. It reads:

"When you use a bonus action to place or move a seal, you can scorch the seals into the target’s soul. For 1 minute, whenever that interdicted creature takes damage, they take extra damage equal to your proficiency bonus"

Is this... is this the only feature of it's kind, especially regarding the fact it works for EVERY HIT and that for EVERY PARTY MEMBER or even on a SUMMON? Or are their more of this kind?

An Oathbreaker paladin has Aura of Hate on level 7, but it only affects them and some undead minions (friend or foe).

What kind of ways can you guys come up with to pair this with? Be it either as a multiclass, a certain spell or a party composition.
