If you go wild with Vit you end up hurting yourself. Why? Because there are 2 penalties for using GC. The first is as stated before, Holy property atk that can be reduced with:
Mag def
Angeling (Total immunity for kick back dmg)
Poopoo
Thara Frog
...etc
And another penalty of 1/5 HP reduction. In other words, if you get a kick back damage of 300 per GC hit, that is 300*3 = 900. So if your max HP is 10,000 , after you GC (Assuming you aren't getting hit at all), first you lose 1/5 of your HP (2000), then you lose the kickback penalty 8000-900 = 7100 HP. Now, how can high vit be bad?
Assuming you are an HP maniac and love having 15,000 HP. When you GC:
15,000 * 20% = 3,000 Dmg
HP reduction penalty = 15,000 - 3000 = 12,000 HP left
Kick back dmg = 1500 Dmg
12,000 - 1,500 = 10,500 HP left
Total HP lost = 4,500
You need 2 lvl 10 heals with max Int to recover that much HP.
Now, when you use another Sader to GC with 9000 max HP:
9,000 * 20% = 1,800 Dmg
HP reduction penalty = 9,000 - 1,800 = 7,200 HP left
Kick back dmg = 900 Dmg
7,200 - 900 = 6,300 HP left
Total HP lost = 2,700
You need 1 lvl 10 heal with max Int to recover most of that HP.
--------------------------------
The first Sader got bigger kickback dmg because he was HP-Based. Using HP gear such as Andre Egg Card in shield and an Int headgear instead of PooPoo hat.
The second sader will be using Thara and Poopoo, that will result in a much smaller kick back dmg.
--------------------------------
Those calculations are done on a Crusader not being hit by anything at all. Now here are some facts that will make you see things much clearer:
1- The first crusader with high Int/Vit has a long cast time due to sacrificing stat points on Int and Vit only. All armor defence is reduced to 2/3 (Down from 30 Def to 20 def, or from 60 Def to 40 def OUCH) WHILE GC being cast. So it is logical to say: The longer you take to cast GC, the more/higher damage you suffer.
2- The second crusader has High int, average vit and relatively high dex. He suffers less kickback dmg, and the 20% HP penalty is smaller because he has less Max HP. Due to the higher dex, you finish casting GC much faster. Meaning if the first Crusader gets hit 2 times before finishing the cast, the second crusader gets hit only once (With reduced defence that is).
3- As I explained earlier, there are two penalties for using GC. Holy property kick back dmg and 20% HP reduction. This HP reduction is based on your CURRENT HP and NOT max HP. Meaning if your max HP is 20,000 and you use GC while your current HP is 5,000 you lose 1,000HP. If your max HP is 8,000 and you use GC with 5,000 HP, you still lose 1,000 HP. The problem arises on high HP values only, where it costs so much SP to go back to full HP.
-----------------------------
Tips:
- Even though Str and Int are the major dmg mechanics, balance is the key.
- Try to go ahead of your mob before you cast GC. Once your monsters are well alligned to their grids and you are sure about their positioning, You can take a couple steps forward and GC, so by the time you unleash GC, the mob just reached you and didn't get to hit you with reduced defence.
- High vit = High dmg from Occult. However, High vit = high HP = bigger chance to survive Asura. But then again, High HP = high HP reduction penalty when GCing. Choose your priorities wisely.
- @mi is your best friend, avoid GCing stuff with high mag def
- Try to use HC or Bash to finish off stuff with low HP that survived your first GC. Even though someone already suggested using lvl 1 GC, but if you use GC, we're still talking about the damned: Def reduction, SP, HP penalty and cast time.
- WATCH HOW YOU POSITION MONSTERS!!!! This is really important. Do your best to make sure no two monsters or more are on the same cell... With practice you'll know why.
Goodluck
Edit:
As for your build, here??is my opinion:
- Endure gives you +10 Magdef. (Less kick back dmg) So if you have a higher Endure lvl and it lasts longer, it'll be better in the long run.
- Using a peco to run fast is good, having a movement-speed over the monsters while mobbing can prove useful. However, when soloing Guard works perfectly.
- Make it 3 + 7 str. From experience, the atk bonus for every 10 str does effect GC dmg.
- I like your Vit, I think you should leave it that way.
Generally I think your build is just great as it is. The only thing I'd recommend is you get a total of 110 base+bonus int. Maybe tune dex a bit down and pump more Int?
Keep in mind, if you use 2 Zerom Gloves you get 8 Dex, if you use 2 Earrings you get 4 Int. If your int is in the 91+ zone, you need 11 stat points per Int point (44 stat points total for 4 Int points). However, if your dex is in the 81~90 you need 10 stat points per dex (80!!! stat points total for 8 Dex points). See the difference in what accessories you use can do? You can save up to 36 stat points.
And Sal, if he uses a Bloody axe, what happens to the (Andre or Zipper Bear Blade/Haed) and the Shield?
