First Pirate to solo zakum ~SeiiShiko~

Even though brandish might be a bit faster, the great part about demo is how you are invincible while casting it and right after you cast it you can probably cast it again which makes you invincible again. What I'm trying to say is that even though brandish might be faster then demo, Demo makes you invincible and is a good way to avoid attacks which is probably why he used such a small amount of pots during the zakum solo. Its the same with Barrage, except barrage has more cooldown time in which you can get hit easier.
