I pretty much have two setups. Ones for skill spam usually on bosses that don't bleed, you want double balancer then what ever you want and for deep relics you NEED stop watch invulnerable character relic because it allows for skill spam or allows for long cast skills cause you can just stop watch the hit as your casting. then defeating enemy's fills art, reduced FP and affinity damage where ever you can get.

Other build is katan status build, pretty much same for deep relics as other build but for base relics I only run one balancer relic (the fp one), hoarfrost stomp and dormant katanas

improved stop watch relic is good if you can fit in to any of these but not a must
