Replace depth charge with aqua lance. Use shark clipped with high tide into aqua lance. Not sure what you are doing that gives you higher parsers with shark but aqualance is more damage. Only use aqua lance into shark when you will use a sc. and even than I wouldn’t recommend it. Shark isn’t working as intended since it doesn’t always crit. It is supposed to have a forced crit attached to it but it doesn’t always crit. But you can take the chance and try to force the crit on vacuum if you want.
