D&D 5E Artificer (Armorer) AC Not Right

Hi team - Using the 5E sheet from Roll20, my player seems to have uncovered an issue... He has built a 6th level Armorer Artificer - the PC has: 16 Dex (so +3) Half-Plate (Medium Armor, base AC15 + max of 2 from Dex) Shield (+2AC) Adds a Feat al L4: Medium Armor Master (allows max of 3 from Dex if they have Medium Armor proficiency - which they do - so adds +1AC) So, the baseline is AC20 . Then he adds two Infusions: Enhanced Defense (+1AC) Repulsion Shield (+1AC if using a Shield, requires Attunement) This would mean their working AC becomes AC22 (I rebuilt the PC in DDB to validate myself and got to the AC22 target)... Except Roll20 is showing AC19! It seems to be ignoring both the Feat and Infusions. I also cannot find anywhere to "turn on" the two infusions, so I guess their adjustments would be manual? Is this a bug, or am I missing something obvious? TIA!

Hi Taz,  Feats are generally not baked into anything in the sheet.  Here is how you resolve all of the above:  Go to the settings icon next to spells.  Third column, near the top, checkmark "Show Global AC Modifier Field" Next, go back to the core page.  In the Global AC Modifier field add entries for Medium Armor Master, Enhanced Defense, and Repulsion Shield. Alternately you can go the equipment route. Such as putting the infusions in as equipment, and changing the base AC of the Half-plate.

However, your proposals are pretty much where I was going for workarounds. Thanks

Thanks Heavy Armor Master should not be adjusting AC as it doesn't affect AC at all. It grants a +1 Strength bonus and reduces damage taken from some sources.

You are quite correct and that is what I meant to say...
