The Permanent Inkbrush is my favorite Brush, ever.

I have a lot of experience with all the brushes, and I can easily say that the PermaBrush is the best Brush for those who want to get in close, stay in close, and cause anarchy wherever they go.

When Splat Bomb Bowling up close, you can throw a bomb where you predict your opponent going, chase after them a bit, ink their feet and deal a bit of damage to them, and let the bomb finish them off in a fluid motion. Got far into enemy turf and in a sticky situation? Throw a bomb, retreat a bit... or Kraken up, be it for offense or defense. Want to play any Ranked mode ever? You know this thing will rock it!

I've been able to stick in enemy turf on Arowana, surrounded by enemies (a Carbon, 52 Gal, and Sploosh-O for example) and without a kraken, for a good 30+ seconds before getting splatted thanks to bomb bowling and my own natural Brushinobi skills... and some swim speed.

If you're the uber-offensive Brush user who likes to stay close to your enemies, this is THE Brush for you. Where every other Brush comes short, one way or the other, it excels. The other Inkbrushes lack the utility of a rollable bomb, though the Nouveau has it's retreat options (which are not offensive in the least). While the Octo has it's Kraken along with natural power, it has to fully rely on the Kraken, which is a bit of an issue. The Octo Nouveau has the Splat Bombs, but in a too-close range, dangerous situation, Inkzooka is not as useful, alongside using too much ink for the bomb to be used in tandem with the brush without some Ink Savers. The Permanent Inkbrush takes all these shortcomings and throws them away. The perfect combination of it's natural swiftness, infinitely utilizable splat bombs, and the perfect offense/defense of a Kraken.

If you're using any other Brush, stop. ... Don't actually, though. Love your current Brush as you will. Each one has it's advantages, but for my playstyle the PermaBrush is Perfect. As I've stated many times, if you like to get in close, stay in close, and flee or counter safely, this is THE brush for you. Just... get some Ink Saver Sub, Swim Speed, Special Generation, and Special Duration first.

Sorry for the long post but I really love this Brush and I'm so happy it exists... honestly IMO it's better than Burst/Rush

tl;dr I love the permabrush and you should too
