I just tried to keep it clean from too much detail since I meant to create that as a summary, not a full-blown guide. You'd use hero weapons at MLB in the end, anyway. Thought it's not worth specifically mentioning for each LB. But to clear things up, just as I mentioned, LB1 & LB2 gives the same burst effect. M-my bad, I guess..?
That's probably because Hraes is 20% & Herc's wep at 1* is 15%.. of the same frame.
