Alright so since Ux Utanar does not auto-fail on 1s on his saves, he auto-passes the Fort and Will saves: (1d20+30)[46] and (1d20+28)[31]. Now, Ereshki rolls for paralysis: (1d20+11)[27]. In case that's an [enchantment] effect, it gains a +4 bonus on that roll due to the Devotion wild cohort bonus.
As far as Fort saves are concerned, Ux Utanar radiates a Draconic aura that grants a +4 bonus to these saves to any ally within 30ft.
Time to roll some offensive dice!
EDIT: man, I had forgotten how forever it takes to type up a post for a high-level character
