Hellzone Grenade
Hellzone Grenade is Piccolo's trap technique. Instead of flying straight at the enemy, its ki blasts spread out to surround the target and then close in on it all at once.
Learning it
Piccolo teaches Hellzone Grenade for 6,000 TP. He has no alignment requirement. Like every ki technique, it needs Ki Control, an empty main hand and at least 5% Power Release, and it must be equipped in a technique slot.
How it works
Hellzone Grenade is a Barrage ki attack: hold the slot key to charge it (2 seconds to reach 100%), keep holding to overcharge up to 175%, and release to fire.
It needs a target: lock on (Z) or aim at one. The ki blasts surround the target and then close in. Its damage is your Ki Damage × 2.5 × the charge.
Upgrades
As a Barrage attack, it gains experience when it hits and can upgrade its damage, speed and cooldown. See Techniques.
