It has become the perception that you need to use lb3 for the second splumes on leviathan.

Pfs wait the extra time to find a mage.

However, i don't think it is needed. Actually i think it's bad to use lb3 on the splumes.
A. You can kill them without any lb.
B. Random party wipes due to splumes dying at same time.
C. can melee lb a splume or save it for last add or to execute leviathan himself.
