I upgraded it 3 pr 4 steps and gave it a try, 780+ dmg dayyymmm. However that is for sure a Multiplayer weapon right, get other to lore in the monster and whack?
Mobility seems to go a long way in this game, so the Glaives jump mechanics is so useful its almost OP but the main reason I started using it was it requires you to hit certain spots on a monsters body to up certain buffs and I thought that mechanic would help me identify and strategize monsters better. I had no idea it would end up being so powerful when buffed and the ability to mount the monster on the fly...mhmm. delicious. Great balance between mobility, dmg and with a defense buff it and free for the tougher monsters its a great single player weapon but most of all is it FUN. I'd nearly wrote this game off s having stamina based souls combat until I tried it.
I've soloed a lot of the monsters so far, but it did require a whole lot of backbreaking farming to be geared sufficiently for that. If you predict some of the monster's movements, you can generally land heavy blows without much difficulty and combo further into some real damage.
I'm not doing Rathalos yet though I did try him a couple of times. Rathian is no longer a problem and I can generally solo her without much effort.
