This guy needs bit less reworking.
First skill: I would simply upgrade dmg ( He is suposed to be a semi dios class right) ^^. That 3X is just useless at this point of the game ( You already have 25 rebirth points, not as though you intend to kill some lousy bandits with that skill)
Second skill: This one is really bad on my opinion, I would actually replace it with a better critico then orc (something like 10% chance to do 3* normal dmg **only on attacks) or 30% chance to do 2*normal dmg on every attack (spell included).
Third skill: Perfect as it is.
Fourth skill: Cool idea the armor. But should be a percentage base spell or something like that (like 5% less armor) So it would still be good against strong boss.
I think with those skills, Hector is really a dmg dealer (because dmg comes more from his arma then his agi).
Feel free to comment ^^.
