Let's do some comparisons from the videos!
Half-Dragon Comparison
AC 18 --> 18
HP 65 --> 105
Speed 30 --> 40 plus a jump bonus action 30ft at the cost of 10ft move
ATK +5 --> +7
DMG 21.3 --> 36
Empyrean Iota (new celestial)
CR 1
AC 13
HP 22 Resistance to all B/P/S
ATK +5
DMG 7
Empyrean Comparison Old --> New
AC 22 --> 22
HP 313 --> 346 with resistance to ALL Bludgeoning/Piercing/Slashing damage
ATK +17 --> +17
DMG 124 --> 186 but two attacks stun OR deal 21 more damage, increasing the possible total to 228!
Initiative +5 --> +19
Very interesting that the PC can choose not to be stunned: *"The target can choose not the be Stunned, in which case it takes an extra 21 Force damage that bypasses Resistance or Immunity" *
