If anyone know please post a reply. I am new to the game. Thank you.
You can buy steel titans from NLC wep seller I know. Not sure where you buy lvl 20 claw...I'm thinking El nath? I do know they sell the lvl 25 claw at El nath though. You can always create your own lvl 20 claw by talking to the wep. creater near the kerning city pq area.
