I see no major loop but a minor one which is probably tied into the subclass naturally.
This exotic is what we need for the Warlock when it comes to specific usage.
Too many exotics within the Warlock kit is too limited in specific to use for what a Warlock is supposed to be or not enough neutral variations.
Vesper of Radius…Bombardiers….Kherpi’s Horn operate the same in usage but 1-2 of these will truthfully see an usage.
