Alchemy is a must if you are Nalpazca, passive choose what you want I guess. For skills I would say, Swift Flurry, Enervating Blows and Heartbeat Drumming are the most important ones and Torment Reach is a great AoE, also don't forget Lesser Wounds and maybe Rooting Pain but that's your choice. With Chanter everything is great, you can use summons that will carry your game or simply use offensive or defensive invocations especially CCs like Paralyze or Charm or buffs/heals. For Chants it depends if you prefer to buff your whole group or your main character but I personally use the burn and slash AoE damage one, 15% burn damage, the healing one or just use whatever you like, everything is really good.
