From D&D Wiki
Small construct, any alignment
Analytic. When the porygon hits a creature with an attack, it has advantage on all attack rolls against that creature until the end of its next turn.
Force Beam. Ranged Spell Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (2d4 + 3) force damage.
Conversion. The porygon gains resistance to one damage type of its choice for 1 minute, or until its concentration is broken (as if concentrating on a spell).
