Skill doing low damage for a Katar-exclusive skill + 1-range skill.
At the moment, the skill is pretty much unusable for a GX because:
1. You CAN'T use a Shield when using this skill
2. You're open to vulnerability since the skill is a 1-range skill
Without buffs = 4k to 4.5k x 8 = 32k to 36k damage
With EDP = 8k to 8.6k x 8 = 64k to 68.8k damage
With EDP + Enchant Poison + Venom Impress debuff = 11k to 13k x 8 = 88k to 104k damage
Considering that the skill is Katar-exclusive, the skill is doing a damage on par with Cross Impact WHICH can be used with any weapon. A probable 20% boost or an additional cast range of 2 for the skill would suffice.
