In a campaign of hells rebel's and I currently have a level 7 halfling inspired blade focused on being the tank for the party. My build is:
Str 8
Dex 18
Con 17
Int 14
Wis 10
Cha 19
Level 1 fencing grace
Level 2 N/A
Level 3 dodge
Level 4 Cautious fighter
Level 5 toughness
Level 6 N/A
Level 7 draconic defender
Bonus feats
Weapon specialization(bonus from GM)
Iron will and Persuasive(bonus from campaign)
At level 8 I plan to take Osyluth's guile since I spent a lot of time defensive fighting to buff AC for myself and allies. I've also considered blundering defense to further go with the buffs.
Relevant gear:
+1 chain shirt
+1 ring of protection
+2 nat armor amulet
unique campaign rapier
+1 buckler
Jingasa(the old/good one)
+1 cloak of resistance
daredevil boots
+4 con belt
+2 charisma headband
Obviously I plan to keep upgrading my gear but I am not really sure what route to go from here to maximize my tank potential.
