I disagree with recommended skill upgrade. Overdrive Kaiten as soon as possible to solve energy issues. The only thing a WP Taka worries is his energy, Clockwork is a waste in my opinion. If you are really in need of energy, upgrade your Void Battery to EoH. Taka's Ki Stacks provide higher CDA than a Clockwork. Sprint Boots are already good for a Taka unless enemies have a Travel Boots, use the upgrade cost for a Travel Boots for more damage or def.
