Well the best way to beat a silver rathalos is with a sonic bow 2 or 3 or above. Since its weakness is electricity, you can bring your felyne for distraction too. I made a link to help more.
You have to complete Extra Ops 121 or 122 (doesn't matter) and damage the wings of Rathalos ( I damaged all the parts like the tail and head just in case). Dont kill Rathalos though, you have to tranquilize Rathalos after you have damaged his body parts. The Musket will then be unlocked once you have completed the mission. The design documents will say "Rathalos Design specs" and when you go back to mother base you will have the musket ready for design. DONT FORGET that you also need to have an R&D member to have Japanese Patriot skill to develope this weapon.
you need rathalos materials, 1 wing, 2 scales, and 3 dragonite ore
you can get the armor in gathering hall hr1 u can get the waist and leggings but i dont know about getting helm and torso and arms
how do unlock silver sable in spiderman friend or foe
while rathalos can fly and lagiacrus can swim i think that the rathalos could because it has the stealth advantage and that rathalos kick butt well not mine with full vangis but well you know I dont know how this will help new hunters it might discourage them but well i got nothing...
no
In Monster Hunter Freedom Unite, you can obtain a Rathalos Ruby as a rare reward by breaking the Rathalos' head or carving its tail after defeating it in a quest. Additionally, capturing the Rathalos also has a chance of yielding a Ruby as a reward. It is a rare drop, so it may take multiple hunts to obtain one.
no
to unlock silver beat up 10 people in 10 min brawl i think
You can't. It is that simple.
there is none. you have to recruit articuno, zapdos, and moltres and then talk to alakazam. you then go to their friend area and they will unlock silver trench.
