Hmm...so from all these items whitch one do you actually recomend most?.Just asking because i want to see your point of view.I am not voting yet,i want to see what you actually think.Also because i see that you took the comments under consideration.Peace :)

dont get magic pen bro

ok il see

Your masteries very much confuse me.

Improved smite? You don't have smite?

Archmage's Savvy? For Pantheon?

As everyone else has said, Pantheon needs survivability now. He also needs mana regen. Your build lacks both.

I would suggest dropping stacking items all together. Get some defensive stats in addition.

0 mana regen from anywhere (even when u say u need it), sword of the occult but no survability, 27 points in the offence tree and not even getting de AMAZING XP boost from Utility.

Bad build methinks, you should check it and try some other things : /

Keep working, and you can improve a lot :)

Not bad, not great... just nice build :)
If you want to play with stacks, you HAVE to buy a Survival item... that culd be Guardian Angel, Banshee's Veil...at least try with Mercury Treads

Bye
