Sura Tiger Cannon Calculation

[javierlog08]

On my server I have a sura with

289166 of HP   But Tigger Cannon is doing 93k of damage without weapon.

I was reading Wiki http://irowiki.org/wiki/Tiger_Cannon

Then I tried to calculate damage following the Formula.

 

SkillMod(%) = [(ConsumedHP + ConsumedSP)/4 * BaseLv/100
+ BonusDamage = TargetLv * 40 + SkillLv * 240

HP = 289166 HP

SP = 2589
Skill Level = 10

Target Level = 175

Caster Level = 175

// First 30% max HP percent
289166 * (10 + skill_level*2) / 100 = 86749.8

// Second lets get SP About same formula at skill level 10

2589 * ( 5 + skill_level) / 100 = 388.35

// Now lets use Skill Formula

(86749.8+388.35) / 4  = 21794.54 Damage

// Lets use Renewall Level Modifer

 21794.54 * (caster level /100) = 38140.45

//Now it says we have a Bonus damage

target level * 40 + skill_level * 240 = 9400

TOTAL DAMAGE : 38140.45 + 9400 = 47540.45

Im not using Weapons and the only skill I'm using before Tiger Cannon is Raising dragon, and Also HP and SP Bonus is added on this formula, with the max HP.

Can someone explain me why it damage 93k? I dont know if my maths are bad

Regards and Thank you guys
