So I've been doing some extensive Pete farming and now have a good amount of seraph crystals. I have the evolution shield but that's it for my seraph purchases. Can anyone recommend any good items? I have all 3 DLCs so all options are in the table. Guns, grenades, shields, relics... tell me your thoughts! Also I've had my eye on a Tumtum Hawkeye and that new corrosive pistol in Hammerlock's DLC. Are these wise purchases? Thanks in advance dudes!
