The Shield Master feat contains this:
If you aren't incapacitated, you can add your shield's AC bonus to any Dexterity saving throw you make against a spell or other harmful effect that targets only you.
The Enhanced Defense infusion of the Artificer contains this:
A creature gains a +1 bonus to Armor Class while wearing (armor) or wielding (shield) the infused item.
The Repulsion Shield infusion of the Artificer contains this:
A creature gains a +1 bonus to Armor Class while wielding this shield.
Assuming I have the Shield Master feat, and I have a regular shield with an AC bonus of +2. If I infuse the shield with either Enhanced Defense or Repulsion Shield, what will my DEX saving throw against spells that target only me be?
Will it be +3 because the infusion increased the shield's AC bonus?
Or will it be +2 because the infusion's AC bonus is the infusion's AC bonus and the shield's AC bonus is still +2?
