The quick respawn investment is pretty self explanatory. Since you might die a lot w/ blaster, quick respawn can help with that. Comeback can definitely come in handy with its small stat boost for every time you get splatted. The single special saver may not look much but it’s pretty essential as it saves a good chunk of your special points when splatted. A single ink resist is also enough as you get the jump boost and damage reduction even without a huge investment. The stealth jump helps you to get back into battle without getting camped, the swim speed helps w/ mobility, super jump is minimal and doesn’t need more than that. So yeah, that’s it, you could go full quick respawn without the special saver & ink resist or the swim speed but I wouldn’t highly recommend it.
