A number of new stats that Summons/Servants can possess separately from their summoners have been adjusted:

Newly Added:
DoT DMG%
Elemental RES PEN
Weakness Break Efficiency
Shield Strength

Stuff they've always had:
ATK/DEF/EHR/ERR Related. Levels. Crits. DMG%. Elemental DMG%. Elemental RES. Healing. BREAK.

Removed:
SPD Related. I guess because the summoner always decides the SPD so the Summon/Servant can't manipulate that
