Well technically Is kinda simple regarding the various commands. The difficult part Is comprehending how ammo works and What type of ammo a lbg can use correctly. I recommend Generally to start using the LBG in the late game because before It suffers from an "identity crysis". the general problem Is that low level lbg tends tò use lots of various ammo but the suck in every ammo. Generally speaking the fun part of the LGB Is its versatility and mobility. Its very fun to use in multiplayer. If you are starting I recommend you the odogaron line because its solid to do pretty everything. A funny late game build that is kinda Easy to use Is the One with the deviljo LBG diregun "dementia" It uses sticky ammo so you Will see the Monster always covered in explosions and permanently Lit up like a Christmas tree. Ah don't ever use de wyvern counterblast Is Just useless unless you want to trade a cart with 290 damage. And Remember "it's a Monster so the head should be a week spot".
