5.5 Battle Smith 4/Eldritch Knight 16 Build Feedback

I was inspired to remake a build from 5.0 that reminded me of my dad (strength through intelligence). Originally, it was going to be a 3/17 split to just get the Artificer subclass for the ability to use intellect to determine melee attack power, but I soon realized Fighters don’t get anything at level 17, and this could be an opportunity to get two epic boons! However, I am concerned this build does not come on until too late because of how long it has to wait for feats/ASIs. Plus, I’m not sure I picked the best feats. I do like how I got both intellect and constitution to 18 at around the same time. Anyway, let me know what you all think!

7: Telekinesis - Intellect 17 to 18

9: Infernal Bulwark - Constitution 16 to 17

11: Infernal Dragoon - Constitution 17 to 18

15: War Caster - Intellect 18 to 19

17: Durable - Constitution 18 to 19

19: Boon of Combat Prowlness - Intellect 19 to 20

20: Boon of Fate - Constitution 19 to 20
