Why do you want to go full CON or SPR ? You don’t need full SPR, you won’t benefit from it.
You also don’t need full CON. You can stay full INT and work on your gear/accessories for extra HP, or put a little bit of CON. If you want to do a lot of PvP you can put more CON though, indeed.
For your skill points
Cleric 2 : You don’t need Safety Zone 10. Safety Zone has an attribute giving you +20 blocks, but the duration of the skill stays the same. So you should go Safety Zone 1-5 instead.
Dievdirbys 3 : Not worth leveling Zemyna that much. -30 SP isn’t a lot. Max World Tree instead.
Miko : You need to max Hamaya 5. It’s the best offensive Miko skill, and it’s really good DPS. Gohei doesn’t need to be leveled.
PD2 : Miko’s Gohei debuffs enemies, so you don’t really need PD’s Disenchant. Your bloodletting is too low, making it not as effective/good.
