The green sword is cap here's how u get the solar sword: So u need to wait 21 mins to get the solar key after that talk to Philp and he will take u to a secret place like that u need to kill the guardian dude and if u kill the guardian dude a door will open and u have to kill the solar dude after that u will get the solar sword (only 2023/2024 summer event don't miss it it will end in August 17) Edit: if u want to get the Halloween sword u have to wait until it's Halloween event see u in the October (Halloween event in B.U.D.S)
Dude if you got the solor key you need to talk to Philip if you didn't do his quest you cannot enter so you need to do his quest use the green sword when I got the solor key I tried talk to him I click his quest because I didn't do his quest
Hey if you want to give V2 on the samurai you have to keep killing him until something pops on your screen it's hard but it's worth it it'll give you "soul mode"
